Explain the heterogenous subunits of Rpb1 by answering these questions. What is the difference between IIo, IIa and IIb? Which enzymes convert IIa to IIo, IIo to IIa and IIa to IIb? Solution Rpb I is a subunit of DNA directed RNA polymerase II which is encoded by POLR2A GENE. IIa - stabilises TATA binding proteins (TBP ) and TAF binding ( TBP associated factors ) . This has one subunit. IIb - this GTF HAS 2 subunits. intermediate in the recruitment of RNA polymerase II. Influences selection of the start point of transcription. This protein would enter the pre initiation complex after TBP. This protein bridges the TATA bound TBP and polymerase. *There appears to be a mistype in IIo as none of the transcription factors are named as IIo, but yes there is a transcription factor as IId. Kindly leave in the comments if that is the same you want details about and feel free to ask any question..

What two kinds of secondary bonds hold polymer chains together Which.pdf
What two kinds of secondary bonds hold polymer chains together? Which is stronger?
Solution
there are three kinds of secondary forces in polymers
1. Polar
2. Hydrogen Bond
3. Non Polar
Out of these three polar bond is more strong because these bond are formed between a
electronegative atom such as oxygen, fluorine and positive atoms like hydrogen and carbon. This
bond has characteristics of Ionic bond and hence it is stronger..

What image of society is held by the three major theoretical approac.pdf
What image of society is held by the three major theoretical approaches? What core questions
does each approach ask? Which of the three approaches strikes you as the most useful? Why?
Solution
The three major theoretical approaches:-
1) Symbolic interactionism
2) Conflict Theory
3) Functionalism
Explanation:-
1) Symbolic interactionism:- emphasises on the language and symbols that help us to give
meaning to the experiences in our life. It is basically slices of society. It is distinctive approach to
the study of human life and human conduct.
2) Conflict Theory:- This theory argues that individuals and groups i.e., social classes within
society have different amounts of material and non-material resources (such as the wealthy vs.
the poor) and that the more powerful groups use their dominance and power in order to exploit
groups with less power.
3) Functionalism:-This theory focuses how everyone take a part in society, how is the behaviour
of the people in the society. It shows the social ethics of an individual. It distinguishes between
good and bad..

Studying Viruses can be important because they are often disease causing pathogens. Howeve,
because of how easy they are to control and mainpulate in the laboratory, viruses can be good
tools to study basic, fundamental principles of cell and molecular biology. Concisely explain one
example of how viruses were used to make a critical molecular genetics discovery (briefly, how
was the experiment done, and what was concluded?)

Solution
Viruses are intracellular parasites that are effective after infecting particular host cells. Viral
infection starts offevolved when proteins on the surface of a virion bind to particular receptor
proteins at the host cells. The specificity of this interaction determines the host range of an
endemic.
Aside from being the causative agents of many sicknesses, viruses are vital gear in cellular
biology research, mainly in research on macromolecular synthesis.
Individual viral particles (virions) usually incorporate both an RNA or a DNA genome,
surrounded via multiple copies of 1 or a small variety of coat proteins, forming the nucleocapsid.
The nucleocapsid of many animal viruses is surrounded with the aid of a phospholipid bilayer, or
envelope.
During lytic replication, host-cell ribosomes and enzymes are used to explicit viral proteins,
which then viral genome and package it into viral coats. The multiple progeny virions produced
within a single infected cellular eventually are launched, following cellular lysis or gradual
disintegration of the cell . Progeny nucleocapsids of enveloped viruses are launched by using
budding of the host-cell membrane in which viral membrane proteins have been deposited.
Some bacterial viruses (bacteriophages) might also go through lysogeny following infection of
host cells. In this situation, the viral genome is incorporated into host-cell chromosomes, forming
a prophage this is replicated along with the host genome. When suitably activated, a prophage
enters the lytic cycle.
All retroviruses and some different animal viruses can combine their genomes into host-cell
chromosomes . In a few instances, this leads to abnormal cell replication and the eventual
improvement of cancers.
Recombinant viruses can be used as vectors to transduce genes into cells. In this method, viral
genes required for the lytic cycle are changed with the aid of other genes. The use of viral
vectors for gene remedy continues to be in its infancy, but has super ability for treatment of
diverse diseases..

Proteins fold. How WhySolutionANSProtein folding Protein.pdf
Proteins fold. How? Why?
Solution
ANS:
Protein folding: Proteins are the molecules in the body which carries out many important
functions, such as enzymes and antibodies.
Before proteins carry out their function, they must first assemble themselves or fold.
PROTEIN FOLDING MODELS:
1. Frame work model:
In this the protein local elements which are stretches of amino acids liked by one another by
covalently with peptide bonds. The region of the primary amino acids sequence in peptide bonds
make different domains.in this domains some of regions are made with Alfa - helix and some are
beta sheet domains.
These primary elements form secondary structure independently of tertiary structure (kim and
baldwin).these elements can diffuse until they collided, successfully adhering and coalescing to
give the tertiary structure (diffus-collision model), (karplus and weaven).
2. The classic nucleation model:
It postulates that some neighboring residues in the sequence would form native secondary
structure that would act as a nucleus form which the native structure would propagate in a step
wise manner. Thus the tertiary structure would form as necessary consequence of the secondary
structure (wetlaufer).
3. Hydrophobic collapse model:
It is hypothesized that a protein would collapse rapidly around its hydrophobic side chain and
then arrange from restricted conformational space occupied by the intermediate. Here the
secondary structure would be directed by native like tertiary structure (ptitsyn & kwajima).
Leviathal’s paradox:
It is formulated by Cyrus Leviathal. It explains, there are vast too many different possible
conformations for a protein to fold by a random search.
Structural organization of protein:
1. Primary Structure: the sequence of amino acids along with the di sulphide bonds.
2. SECONDARY STRUCTURE:
Alfa Helices and Beta- Pleated sheets are most frequently occur in secondary structure in
polypeptides. Both of these can case local folding of protein.
The Alfa Helices in polypeptide made up of L- Alfa amino acids are right handed, the Alfa -
Helices is stabilized by hydrogen bonds formed between oxygen and amide hydrogen’s of
peptide bonds that are a part of linear sequence.
Beta- Pleated sheets: 2 types
A. Parallel: in this the adjacent hydrogen bonding segments are connected by cross over
connection [Right handed].
B. Anti-Parallel: In this the adjacent hydrogen bonding segments are connected by HAIRPIN
turns or reverse turn [Left Handed].
3. Tertiary structure: It is arisen because of the folding of poly peptides upon itself.
4. Quaternary structure:
Some proteins are made up of 2 or more polypeptides chains, the interaction between different
poly peptide are subunits gives rise to the quaternary structure..
PLN 360560 Environmental Impact Assessment Homework No. 4 1. An appl.pdf
PLN 360/560 Environmental Impact Assessment Homework No. 4 1. An applicant has applied
to the U.S. Army Corps of Engineers (USACE) for a Clean Water Act (CWA) Section 404
Permit to construct a marina at the mouth of Chaotic Creek on Bagel Bay on Lake Promise, a
Water of the United States and Class \"B\" surface water in New York State. This site is located
in the upper reach of a large commercial harbor used for deep-draft navigation. The project
entails (1) construction of a breakwall; (2) dredging (and future maintenance dredging) of
navigation entrance and creek channels; (3) installation of 50 docks with boat slips; and (4)
construction of a boat launching ramp. During construction, it is estimated that a total of 60,000
cubic yards of material will be dredged and need to be managed, and about 2,500 cubic yards of
fill will need to be placed in Lake Promise. Management alternatives for the dredged material
include placement at an upland permitted municipal landfill, or discharge at a designated open-
water site in the harbor. The site is an abandoned \"hole\" and since discharge of the dredged
sediment is conceived to have benefits through reducing DDE bioaccumulation through capping
and restoration of shallow water aquatic habitat, it is referred to as a habitat restoration site
(HRS). The applicant had a consultant sample the sediments to be dredged for the marina as well
as a lake reference area and HRS, and had the samples analyzed by a laboratory. The following
is a summary of the test results that are to be submitted with the application: Contaminant

one of the main design goals for the java programming language is se.pdf
one of the main design goals for the java programming language is security. Explain, in detail
how java achieves this goal?
Solution
1.Security became an essential piece of a java language from the starting day itself.Additionally
it is an progressing design aim of the java community .An intrinsic security is observed ,hence
the java language is in much now-a-days which is the major cause.
2.Every action is possible through Java virtual machine(JVM) .it is mainly to establish the
attributes like trust,integrity,confidentiality..etc.
3.Java offers large compile perusal ,leads with secondary stage of examining .language attributes
motivates the programmers closely to good programming recurents. especially the memory
management representation is uncomplicated.it removes the total classes of programing mistakes
which causes a continous trouble to the C and C++ programmers.moreover the objects are
fabricated with a new operator.precised programmer defined pointer data types, pointer
arthematic and self-activated garbage collector is absent.
4.java language is manipulated in distributed domains that tells that the security is most
important including the security attributes which is intended in the java language and run time
system.
5.In case of network habitats ,the applications in java language are secured from interruption
with an unofficial code venturing to acheive alrady the scenes and occupy file systems..
Meyer and colleagues performed three rounds of X-ray crystallography.pdf
Meyer and colleagues performed three rounds of X-ray crystallography, each with a different
elastase crystal. For each experiment, they positioned the elastase crystal at a different angle.
Why might researchers have rotated elastase crystals to position them at different angles?
Select one:
a. Similar to when you get X-rayed in different positions, X-rays would produce different images
depending on the angle and position of the elastase crystal. Researchers likely rotated elastase
crystals to different angles to understand the conformation of this enzyme from all sides.
b. There was no reason for the researchers to rotate the elastase crystals. It would have been
sufficient to carry out one X-ray crystallography experiment on an elastase crystal.
c. Rotating the elastase crystals to different angles likely affected the rate of the enzymatic
reaction; at a different angle, the hexapeptide substrate could remain bound to elastase for a
longer period of time. There was thus more time to get detailed X-ray images.
Solution
a.Similar to when you get X-rayed in different positions,X-rays would produce different images
depending on the angle and the position of the elactase crystal.Researchers likely rotated elastase

Numerous diseases are caused by problems in DNA replication or repai.pdf
Numerous diseases are caused by problems in DNA replication or repair. For example, Bloom
Syndrome is caused by a mutation in one of the helicase enzymes involved in DNA replication.
Select one of the enzymes involved in DNA replication or repair and find a disease related to a
mutation in this enzyme (a few of these diseases are mentioned in your textbook). Then, in at
least 3 pages, address the following topics: 1. What is the specific mutation? 2. What are the
symptoms of the disease? 3. How was the relationship between the mutation and the disease
discovered? 4. How does this mutation impact DNA replication and repair and how is this
different from normal DNA replication? 5. How does this mutation impact transcription and
translation and how is this different from normal transcription and translation? 6. How does this
problem in DNA replication lead to one symptom of the disease? 7. Give two examples of how
genetic engineering technology could be used to learn more about, detect earlier, or treat this
disease? Be sure to include a description of what genetic engineering is. You should write this
Assignment as an integrated paper that addresses all the questions. This Assignment should not
be done in question and answer format. Be sure to use appropriate headings for each section of
the paper.
Solution
Disease caused :Progressive external ophthalmoplegia (PEO) is caused by mutations in
mitochondrial DNA.
1.Specific mutation:Human mitochondrial DNA replication takes place by two-subunitsof DNA
polymerase gamma (polgamma).Mutations in the polymerase and exonuclease domains of the
human polgamma is the cause behind the occurence of PEO.
2.Symptoms of the disease:
3.Discovery of the relationship between DNA replication and repair: The diseases was
discovered the symptoms that the patients experience followed by a genetic test on muscle
biopsy sample.This led to the conclusion that there occured several deletions inmitochondrial
DNA.Research further revealed that there occured mutations in polgamma on chrmosome
15q25.In particular, three autosomal dominant mutations were revealed that altered the amino
acids located within polymerase motif B of polgamma.
4.Impact of mutation on DNA replication: The mutation resulted in dysfunctioning of the
polgamma and thus some regions of the mitochondrial DNA are deleted in comparision to
normal replication where the entire mitochondrial DNA is replicated fully.
5.Impact on transcription and translation: Mitochondrial DNA encodes 13 protein subunits of
multimeric oxidative phosphorylation, 2 ribosomal RNAs and all the translated RNAs that are
required for the translation of its own messenger RNA.In presence of mutations, some regions of
mitochindrial DNA is not replicated and this leads to impaired protein synthesis.
6.Problem in DNA replication lead to one symptom of the disease: Deletions in segments of
mitochondrial DNA leads to defective function of oxidative phosphorylation due to impaired
protein synth.
In the Mexican swordtail fish, the wild-type color is olive-green. Ot.pdf
In the Mexican swordtail fish, the wild-type color is olive-green. Other color variants include
golden and Take caution with ratio there is some reduced viability in this system. Matings
involving fish of these three phenotypes are shown below: Explain the inheritance of these color
phenotypes in the fish
Solution
At any rate, the mode of inheritance of albinism in the goldfish has not hitherto been known.
Using mates of different varieties of the goldfish, scientists arrived at the conclusion that
albinism of the goldfish is not a simple Mendelian character but it is represented by the double
homozygote of two non-linked autosomal recessive genes since because the F2 generation shows
15:1 ratio for non-albino and albino types like we see in the case of duplicate genes.
example: If the animal was A/a, because a is recessive and A is dominant, the animal\'s
phenotype wouldn\'t be albino, but it would still carry the gene for albinism (since it has an
\"a\"). Since it carries both \"A\" and \"a\", it is known as \"heterozygous\". If the animal had the
A/A combination, its phenotype wouldn\'t be albino, and it wouldn\'t carry the gene for albinism
(both genes being the same, it is called \"homozygous\" for \"A\"). If it were homozygous for
\"a\" (i.e. a/a), the animal\'s phenotype would be albino. Since \"a\" is recessive, both alleles need
to be \"a\" in order for albinism to be expressed in the phenotype.
The genes for the pigment cells are inherited independently of one another, and there is no
known linkage to any other genes. So, each pigment type is coded by two different genes, one on
each of a pair of chromosomes. The phenotype of wild type animals is dark, non-melanoid, non-
albino and non-axanthic.
The golden colour (D/D a/a or D/d a/a). It has normal migration of pigment cells, but lacks
melanophores, hence the yellow/gold appearance..
If we maintain a strict biological definition of “species”, H. sapie.pdf
If we maintain a strict biological definition of “species”, H. sapiens and H. neanderthalensis were
NOT separate species as they successfully interbred. What impact might this information have
on assigning a date to the origin of humans? Are there any other implications?
Solution
As we know the common male ancester is usually much younger than the common female
ancester.Moreover the Mitochondrial DNA which is present in the Neanderthals and it is absent
in humans
Suppose we have related populations A, B and C and we can have that A can interbreed with B,
and also the B can interbreed with C,.At the same time ,A can not interbreed with C. Noe a
ccording to the strict BSC, the A and B are in the same species and at the same time B and C are
in the same species, but A and C are not.These are the implications
here.
It is impossible to know the date of origins of humans due to difference between sapiens and
neanderthals.we can fix one date on which an old species was found and can assume it to be the
date of origin..
If taxpayers Monica, Traci , and Phillip are responsible persons in .pdf
If taxpayers Monica, Traci , and Phillip are responsible persons in the failure to withhold and pay
over employment taxes but only Monica and Traci acted willfully which of the following
statements is correct? A the IRs may assess the trust fund recovery penalty against Monica ,
Traci and Phillip, but can only collect it from Monica and Traci b. The IRS can only asses and
collect a trust fund recovery penalty from Phillip c. The IRS cannot assess a trust find recovery
penalty against Phillip d. the IRS may asses a trust fund recovery penalty against Monica , Traci,
and Phillip
Solution
The tax IRs may assess a trust recovery penalty against monica, traci, and phillip, but can only
collect it from monica and trici.
The employer need to withhold taxes from its employees wages and pay them to IRS. Withheld
taxes are been said as trust fund taxes. When these taxes are not paid by the employer
intenstionally or not to get paid the taxes IRs checks for the responsible person and willful
person and upon all IRs may assess for thr trust fund recovery. IRs may ask for to pay the
penality by any of the responsible persons..

Answer:
Observation 1: Common cold is caused by bacterial or viral infection and transmitted from one
person to other through droplets from infected person. The person infected with common cold
show protect his nose or mouth with steril mask, which covers mouth and nose. If nose or mouth
is not covered by mask, droplets can transmit common cold to many people in surrounding
environment.
Observation 2: Common cold is widely transmitted very easily, if a person infected with
common cold and he sneezes in public places which is having high population, several thousands
of droplets can be transported through air at onetime, when person sneezes, so avoid moving in
public places when common cold is rampant in specific area.
Observation 3: Doctors who examine the persons suffering with common cold should be careful,
the physician should use antibiotics or vaccines to prevent common cold infection..

INTRODUCTION:
Ethylcellulose polymer is widely used in pharmaceutical coating, especially when producing
modified release
dosage forms. Drug release through barrier membrane systems is influenced by several process
and
formulation variables; however, our understanding of the influence of these variables is hindered
by a lack of
comprehensive models to guide our coating efforts. The purpose of this work was to study the
influence of an
aqueous or an organic coating process on drug release profile characteristics from an
ethylcellulose barrier
membrane coated multiparticulate system.
Either ETHOCEL ethylcellulose (Standard 20 Premium, The Dow Chemical Company) or
aqueous
ethylcellulose dispersion (Surelease E-7-19040, Colorcon, USA) was used as the barrier
membrane polymer.

Di Paoloma University had a faculty reduction and lost 15 of its fa.pdf
Di Paoloma University had a faculty reduction and lost 1/5 of its faculty. If 320 faculty members
were left after the reduction, how many members were there originally?
Solution
1/5 means 20% is the left out faculty which is 320.
So, 100% that is initially available is 100/20*320=1600.
Originally 1600 faculty were there..
Define a relation R on the set Z of all integers by a R b if and only.pdf
Define a relation R on the set Z of all integers by a R b if and only if 3a + b is a multiple of 4.
Prove that R is an equivalence relation. Determine the equivalence classes associated with R.
Solution
1. 3a+a=4a
Hence, aRa for all integers a
Hence, R is reflexive
2. Let, aRb
So
3a+b= multiple of 4
3(3a+b)=3b+9a is multiple of 4
3b+a+8a is multiple of 4
Hence, 3b+a is multiple of 4
Hence,bRa
So, R is symmetric
3. Let, aRb and bRc
3a+b is multiple of 4, 3b+c is multipe of 4
So,
3a+b+3b+c =3a+c+4b is multiple of 4
HEnce, 3a+c is multiple of 4
So, aRc
Hence, R is equivalence relation
3a+b=4a-a+b
Hence, 4a+(b-a) is multiple of 4
ie b-a is multipel of 4
Hence all elemenets of an equivalence class are one which give same remainder modulo 4
so there are 4 equivalence classes for each remainder modulo 4 ie [0],[1],[2],[3].

example of how viruses were used to make a critical molecular genetics discovery (briefly, how

Solution
Viruses are intracellular parasites that are effective after infecting particular host cells. Viral
infection starts offevolved when proteins on the surface of a virion bind to particular receptor
proteins at the host cells. The specificity of this interaction determines the host range of an
endemic.
Aside from being the causative agents of many sicknesses, viruses are vital gear in cellular
biology research, mainly in research on macromolecular synthesis.
Individual viral particles (virions) usually incorporate both an RNA or a DNA genome,
surrounded via multiple copies of 1 or a small variety of coat proteins, forming the nucleocapsid.
The nucleocapsid of many animal viruses is surrounded with the aid of a phospholipid bilayer, or
envelope.
During lytic replication, host-cell ribosomes and enzymes are used to explicit viral proteins,
which then viral genome and package it into viral coats. The multiple progeny virions produced
within a single infected cellular eventually are launched, following cellular lysis or gradual
disintegration of the cell . Progeny nucleocapsids of enveloped viruses are launched by using
budding of the host-cell membrane in which viral membrane proteins have been deposited.
Some bacterial viruses (bacteriophages) might also go through lysogeny following infection of
host cells. In this situation, the viral genome is incorporated into host-cell chromosomes, forming
a prophage this is replicated along with the host genome. When suitably activated, a prophage
enters the lytic cycle.
All retroviruses and some different animal viruses can combine their genomes into host-cell
chromosomes . In a few instances, this leads to abnormal cell replication and the eventual
improvement of cancers.
Recombinant viruses can be used as vectors to transduce genes into cells. In this method, viral
genes required for the lytic cycle are changed with the aid of other genes. The use of viral
vectors for gene remedy continues to be in its infancy, but has super ability for treatment of
diverse diseases..

Proteins fold. How WhySolutionANSProtein folding Protein.pdf
Proteins fold. How? Why?
Solution
ANS:
Protein folding: Proteins are the molecules in the body which carries out many important
functions, such as enzymes and antibodies.
Before proteins carry out their function, they must first assemble themselves or fold.
PROTEIN FOLDING MODELS:
1. Frame work model:
In this the protein local elements which are stretches of amino acids liked by one another by
covalently with peptide bonds. The region of the primary amino acids sequence in peptide bonds
make different domains.in this domains some of regions are made with Alfa - helix and some are
beta sheet domains.
These primary elements form secondary structure independently of tertiary structure (kim and
baldwin).these elements can diffuse until they collided, successfully adhering and coalescing to
give the tertiary structure (diffus-collision model), (karplus and weaven).
2. The classic nucleation model:
It postulates that some neighboring residues in the sequence would form native secondary
structure that would act as a nucleus form which the native structure would propagate in a step
wise manner. Thus the tertiary structure would form as necessary consequence of the secondary
structure (wetlaufer).
3. Hydrophobic collapse model:
It is hypothesized that a protein would collapse rapidly around its hydrophobic side chain and
then arrange from restricted conformational space occupied by the intermediate. Here the
secondary structure would be directed by native like tertiary structure (ptitsyn & kwajima).
Leviathal’s paradox:
It is formulated by Cyrus Leviathal. It explains, there are vast too many different possible
conformations for a protein to fold by a random search.
Structural organization of protein:
1. Primary Structure: the sequence of amino acids along with the di sulphide bonds.
2. SECONDARY STRUCTURE:
Alfa Helices and Beta- Pleated sheets are most frequently occur in secondary structure in
polypeptides. Both of these can case local folding of protein.
The Alfa Helices in polypeptide made up of L- Alfa amino acids are right handed, the Alfa -
Helices is stabilized by hydrogen bonds formed between oxygen and amide hydrogen’s of
peptide bonds that are a part of linear sequence.
Beta- Pleated sheets: 2 types
A. Parallel: in this the adjacent hydrogen bonding segments are connected by cross over
connection [Right handed].
B. Anti-Parallel: In this the adjacent hydrogen bonding segments are connected by HAIRPIN
turns or reverse turn [Left Handed].
3. Tertiary structure: It is arisen because of the folding of poly peptides upon itself.
4. Quaternary structure:
Some proteins are made up of 2 or more polypeptides chains, the interaction between different
poly peptide are subunits gives rise to the quaternary structure..

PLN 360/560 Environmental Impact Assessment Homework No. 4 1. An applicant has applied
to the U.S. Army Corps of Engineers (USACE) for a Clean Water Act (CWA) Section 404
Permit to construct a marina at the mouth of Chaotic Creek on Bagel Bay on Lake Promise, a
Water of the United States and Class \"B\" surface water in New York State. This site is located
in the upper reach of a large commercial harbor used for deep-draft navigation. The project
entails (1) construction of a breakwall; (2) dredging (and future maintenance dredging) of
navigation entrance and creek channels; (3) installation of 50 docks with boat slips; and (4)
construction of a boat launching ramp. During construction, it is estimated that a total of 60,000
cubic yards of material will be dredged and need to be managed, and about 2,500 cubic yards of
fill will need to be placed in Lake Promise. Management alternatives for the dredged material

one of the main design goals for the java programming language is se.pdf
one of the main design goals for the java programming language is security. Explain, in detail
how java achieves this goal?
Solution
1.Security became an essential piece of a java language from the starting day itself.Additionally
it is an progressing design aim of the java community .An intrinsic security is observed ,hence
the java language is in much now-a-days which is the major cause.
2.Every action is possible through Java virtual machine(JVM) .it is mainly to establish the
attributes like trust,integrity,confidentiality..etc.
3.Java offers large compile perusal ,leads with secondary stage of examining .language attributes
motivates the programmers closely to good programming recurents. especially the memory
management representation is uncomplicated.it removes the total classes of programing mistakes
which causes a continous trouble to the C and C++ programmers.moreover the objects are
fabricated with a new operator.precised programmer defined pointer data types, pointer
arthematic and self-activated garbage collector is absent.
4.java language is manipulated in distributed domains that tells that the security is most
important including the security attributes which is intended in the java language and run time
system.
5.In case of network habitats ,the applications in java language are secured from interruption
with an unofficial code venturing to acheive alrady the scenes and occupy file systems..
Meyer and colleagues performed three rounds of X-ray crystallography.pdf
Meyer and colleagues performed three rounds of X-ray crystallography, each with a different
elastase crystal. For each experiment, they positioned the elastase crystal at a different angle.
Why might researchers have rotated elastase crystals to position them at different angles?
Select one:
a. Similar to when you get X-rayed in different positions, X-rays would produce different images
depending on the angle and position of the elastase crystal. Researchers likely rotated elastase
crystals to different angles to understand the conformation of this enzyme from all sides.
b. There was no reason for the researchers to rotate the elastase crystals. It would have been
sufficient to carry out one X-ray crystallography experiment on an elastase crystal.
c. Rotating the elastase crystals to different angles likely affected the rate of the enzymatic
reaction; at a different angle, the hexapeptide substrate could remain bound to elastase for a
longer period of time. There was thus more time to get detailed X-ray images.
Solution
a.Similar to when you get X-rayed in different positions,X-rays would produce different images
depending on the angle and the position of the elactase crystal.Researchers likely rotated elastase

Numerous diseases are caused by problems in DNA replication or repai.pdf
Numerous diseases are caused by problems in DNA replication or repair. For example, Bloom
Syndrome is caused by a mutation in one of the helicase enzymes involved in DNA replication.
Select one of the enzymes involved in DNA replication or repair and find a disease related to a
mutation in this enzyme (a few of these diseases are mentioned in your textbook). Then, in at
least 3 pages, address the following topics: 1. What is the specific mutation? 2. What are the
symptoms of the disease? 3. How was the relationship between the mutation and the disease
discovered? 4. How does this mutation impact DNA replication and repair and how is this
different from normal DNA replication? 5. How does this mutation impact transcription and
translation and how is this different from normal transcription and translation? 6. How does this
problem in DNA replication lead to one symptom of the disease? 7. Give two examples of how
genetic engineering technology could be used to learn more about, detect earlier, or treat this
disease? Be sure to include a description of what genetic engineering is. You should write this
Assignment as an integrated paper that addresses all the questions. This Assignment should not
be done in question and answer format. Be sure to use appropriate headings for each section of
the paper.
Solution
Disease caused :Progressive external ophthalmoplegia (PEO) is caused by mutations in
mitochondrial DNA.
1.Specific mutation:Human mitochondrial DNA replication takes place by two-subunitsof DNA
polymerase gamma (polgamma).Mutations in the polymerase and exonuclease domains of the
human polgamma is the cause behind the occurence of PEO.
2.Symptoms of the disease:
3.Discovery of the relationship between DNA replication and repair: The diseases was
discovered the symptoms that the patients experience followed by a genetic test on muscle
biopsy sample.This led to the conclusion that there occured several deletions inmitochondrial
DNA.Research further revealed that there occured mutations in polgamma on chrmosome
15q25.In particular, three autosomal dominant mutations were revealed that altered the amino
acids located within polymerase motif B of polgamma.
4.Impact of mutation on DNA replication: The mutation resulted in dysfunctioning of the
polgamma and thus some regions of the mitochondrial DNA are deleted in comparision to
normal replication where the entire mitochondrial DNA is replicated fully.
5.Impact on transcription and translation: Mitochondrial DNA encodes 13 protein subunits of
multimeric oxidative phosphorylation, 2 ribosomal RNAs and all the translated RNAs that are
required for the translation of its own messenger RNA.In presence of mutations, some regions of
mitochindrial DNA is not replicated and this leads to impaired protein synthesis.
6.Problem in DNA replication lead to one symptom of the disease: Deletions in segments of
mitochondrial DNA leads to defective function of oxidative phosphorylation due to impaired
protein synth.
In the Mexican swordtail fish, the wild-type color is olive-green. Ot.pdf
In the Mexican swordtail fish, the wild-type color is olive-green. Other color variants include
golden and Take caution with ratio there is some reduced viability in this system. Matings
involving fish of these three phenotypes are shown below: Explain the inheritance of these color
phenotypes in the fish
Solution
At any rate, the mode of inheritance of albinism in the goldfish has not hitherto been known.
Using mates of different varieties of the goldfish, scientists arrived at the conclusion that
albinism of the goldfish is not a simple Mendelian character but it is represented by the double
homozygote of two non-linked autosomal recessive genes since because the F2 generation shows
15:1 ratio for non-albino and albino types like we see in the case of duplicate genes.
example: If the animal was A/a, because a is recessive and A is dominant, the animal\'s
phenotype wouldn\'t be albino, but it would still carry the gene for albinism (since it has an
\"a\"). Since it carries both \"A\" and \"a\", it is known as \"heterozygous\". If the animal had the
A/A combination, its phenotype wouldn\'t be albino, and it wouldn\'t carry the gene for albinism
(both genes being the same, it is called \"homozygous\" for \"A\"). If it were homozygous for
\"a\" (i.e. a/a), the animal\'s phenotype would be albino. Since \"a\" is recessive, both alleles need
to be \"a\" in order for albinism to be expressed in the phenotype.
The genes for the pigment cells are inherited independently of one another, and there is no
known linkage to any other genes. So, each pigment type is coded by two different genes, one on
each of a pair of chromosomes. The phenotype of wild type animals is dark, non-melanoid, non-
albino and non-axanthic.
The golden colour (D/D a/a or D/d a/a). It has normal migration of pigment cells, but lacks
melanophores, hence the yellow/gold appearance..
If we maintain a strict biological definition of “species”, H. sapie.pdf
If we maintain a strict biological definition of “species”, H. sapiens and H. neanderthalensis were
NOT separate species as they successfully interbred. What impact might this information have
on assigning a date to the origin of humans? Are there any other implications?
Solution
As we know the common male ancester is usually much younger than the common female
ancester.Moreover the Mitochondrial DNA which is present in the Neanderthals and it is absent
in humans
Suppose we have related populations A, B and C and we can have that A can interbreed with B,
and also the B can interbreed with C,.At the same time ,A can not interbreed with C. Noe a
ccording to the strict BSC, the A and B are in the same species and at the same time B and C are
in the same species, but A and C are not.These are the implications
here.
It is impossible to know the date of origins of humans due to difference between sapiens and
neanderthals.we can fix one date on which an old species was found and can assume it to be the
date of origin..
If taxpayers Monica, Traci , and Phillip are responsible persons in .pdf
If taxpayers Monica, Traci , and Phillip are responsible persons in the failure to withhold and pay
over employment taxes but only Monica and Traci acted willfully which of the following
statements is correct? A the IRs may assess the trust fund recovery penalty against Monica ,
Traci and Phillip, but can only collect it from Monica and Traci b. The IRS can only asses and
collect a trust fund recovery penalty from Phillip c. The IRS cannot assess a trust find recovery
penalty against Phillip d. the IRS may asses a trust fund recovery penalty against Monica , Traci,
and Phillip
Solution
The tax IRs may assess a trust recovery penalty against monica, traci, and phillip, but can only
collect it from monica and trici.
The employer need to withhold taxes from its employees wages and pay them to IRS. Withheld
taxes are been said as trust fund taxes. When these taxes are not paid by the employer
intenstionally or not to get paid the taxes IRs checks for the responsible person and willful
person and upon all IRs may assess for thr trust fund recovery. IRs may ask for to pay the
penality by any of the responsible persons..

Solution
Answer:
Observation 1: Common cold is caused by bacterial or viral infection and transmitted from one
person to other through droplets from infected person. The person infected with common cold
show protect his nose or mouth with steril mask, which covers mouth and nose. If nose or mouth
is not covered by mask, droplets can transmit common cold to many people in surrounding
environment.
Observation 2: Common cold is widely transmitted very easily, if a person infected with
common cold and he sneezes in public places which is having high population, several thousands
of droplets can be transported through air at onetime, when person sneezes, so avoid moving in
public places when common cold is rampant in specific area.
Observation 3: Doctors who examine the persons suffering with common cold should be careful,
the physician should use antibiotics or vaccines to prevent common cold infection..

INTRODUCTION:
Ethylcellulose polymer is widely used in pharmaceutical coating, especially when producing
modified release
dosage forms. Drug release through barrier membrane systems is influenced by several process
and
formulation variables; however, our understanding of the influence of these variables is hindered
by a lack of
comprehensive models to guide our coating efforts. The purpose of this work was to study the
influence of an
aqueous or an organic coating process on drug release profile characteristics from an
ethylcellulose barrier
membrane coated multiparticulate system.
Either ETHOCEL ethylcellulose (Standard 20 Premium, The Dow Chemical Company) or
aqueous
ethylcellulose dispersion (Surelease E-7-19040, Colorcon, USA) was used as the barrier
membrane polymer.

Di Paoloma University had a faculty reduction and lost 15 of its fa.pdf
Di Paoloma University had a faculty reduction and lost 1/5 of its faculty. If 320 faculty members
were left after the reduction, how many members were there originally?
Solution
1/5 means 20% is the left out faculty which is 320.
So, 100% that is initially available is 100/20*320=1600.
Originally 1600 faculty were there..
Define a relation R on the set Z of all integers by a R b if and only.pdf
Define a relation R on the set Z of all integers by a R b if and only if 3a + b is a multiple of 4.
Prove that R is an equivalence relation. Determine the equivalence classes associated with R.
Solution
1. 3a+a=4a
Hence, aRa for all integers a
Hence, R is reflexive
2. Let, aRb
So
3a+b= multiple of 4
3(3a+b)=3b+9a is multiple of 4
3b+a+8a is multiple of 4
Hence, 3b+a is multiple of 4
Hence,bRa
So, R is symmetric
3. Let, aRb and bRc
3a+b is multiple of 4, 3b+c is multipe of 4
So,
3a+b+3b+c =3a+c+4b is multiple of 4
HEnce, 3a+c is multiple of 4
So, aRc
Hence, R is equivalence relation
3a+b=4a-a+b
Hence, 4a+(b-a) is multiple of 4
ie b-a is multipel of 4
Hence all elemenets of an equivalence class are one which give same remainder modulo 4
so there are 4 equivalence classes for each remainder modulo 4 ie [0],[1],[2],[3].

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Explain the heterogenous subunits of Rpb1 by answering these questio.pdf
- 1. Explain the heterogenous subunits of Rpb1 by answering these questions. What is the difference between IIo, IIa and IIb? Which enzymes convert IIa to IIo, IIo to IIa and IIa to IIb? Solution Rpb I is a subunit of DNA directed RNA polymerase II which is encoded by POLR2A GENE. IIa - stabilises TATA binding proteins (TBP ) and TAF binding ( TBP associated factors ) . This has one subunit. IIb - this GTF HAS 2 subunits. intermediate in the recruitment of RNA polymerase II. Influences selection of the start point of transcription. This protein would enter the pre initiation complex after TBP. This protein bridges the TATA bound TBP and polymerase. *There appears to be a mistype in IIo as none of the transcription factors are named as IIo, but yes there is a transcription factor as IId. Kindly leave in the comments if that is the same you want details about and feel free to ask any question.
