With which portion of an epithelial cell in the stomach would food be.pdf
With which portion of an epithelial cell in the stomach would food be in contact? basal surface
basement membrane tight junctions apical surface gap junctions Which of the following
relationships between a tissue and its general function is not correct? Epithelial: control Nerve:
control Connective: support Muscle: movement Goblet cells are found in which of these
epithelia. Stratified squmous Simple squmaous Transitional Simple columnar
Solution
1. apical surface
The stomach surface is lined with mucus secreting columnar epithelial cells. A single
cell structure consists of three surfaces-apical, lateral and basal.
The apical surface faces the intestinal lumen. Extending from the apical surface are
numerous fingerlike projections (100 nm in diameter) called microvilli, referred as the brush
border due to their appearance. Microvilli greatly increase the area of the apical surface,
enhancing the absorptive and transportive capacity of the intestinal epithelium. Overlying the
brush border, are the oligosaccharide side chains of integral membrane glycoproteins,
glycolipids, and enzymes (glycocalyx) catalyzing the final digestion of ingested carbohydrates
and proteins. The resultant monosaccharides and amino acids produced are transported across the
intestinal epithelium and eventually into the bloodstream.
The lateral surface encloses tight junctions, adherens junctions, spotdesmosome, gap
junction, intermediate filament, and hemidesmosome.
-Tight junctions, prevent diffusion of substances between the intestinal lumen and the blood via
the extracellular space between cells. They function as a selective and semipermeable barrier
between apical and basolateral compartments of the epithelial layer. They facilitate the passage
of small ions and water-soluble solutes through the paracellular space while preventing the
passage of luminal antigens, microorganisms and their toxins.
-Gap junctions are door-like connections between each epithelial cells.They allow movement of
small molecules and ions between the cytosol of adjacent cells.
-The remaining three types of junctions, adherens junctions, spot desmosomes, and
hemidesmosomes are critical to cell-cell and cell-matrix adhesion.
The basal surface of the epithelial cells is the basal lamina, consisting of a fibrous
network of collagen and proteoglycans that supports the epithelial cell layer.
2. epithelial:control
Epithelial cells line the body cavities and surface of organs and blood vessels. Their functions
include secretion, selective absorption, protection, transcellular transport, and sensing.
3. simple columnar
Goblet cells are found scattered among the epithelial cells, mostly in the respiratory and
intestinal tracts. These cells are simple columnar epithelial cells with a narrow base and
expanded apical portion (glandular shape). They secrete mucus which protect against stress and
chemical damage, and destroy the microorganisms and particulate matter..

You are carrying out PCRs in lab. Why do you not need helicase, SSB,.pdf
You are carrying out PCRs in lab. Why do you not need helicase, SSB, primase, ligase, sliding
clamp?
Solution
1. Helicase: Helicase is an eznyme that plays a crucial role in seperating the DNA double helix
by unwinding it.
2. SSB: It stands for Single-Stranded DNA Binding Protein (SSB). It binds with high affinity to
single-stranded DNA and destabilizes helical duplexes. This helps DNA polymerases to bind to
substrates easily. SSB do not bind to double stranded DNAs.
3. Primase: Primase is an enzyme that synthesize primers (short stretches of DNA for the DNA
synthesis to proceed) in vivo. In In a PCR experiment, two specific primers are designed and
added in the reaction for amplifying specific sequences.
4. Ligase: This enzyme catalyze the DNA repair process by joining of ends of DNA molecules.
In these reactions, this enzyme links the phosphate to a neighboring sugar molecule, thus
forming the backbone of DNA.
5. Sliding clamp: This clamp protein binds to DNA polymerase (enyme synthesizing the DNA
chain), and prevents it from dissociation from the template. Thus it acts as a promoting factor in
DNA replication process. The clamp-polymerase interactions are stronger and more specific. It
increases the rate of reaction progression..

Which of the following correctly states the functions of the roug.pdf
Which of the following correctly states the functions of the rough endoplasmic reticulum ? lipid
metabolism, cholesterol synthesis, and synthesis of the lipid components of lipoproteins
absorption, synthesis, and transport of fats. storage of calcium ions synthesis of the cell\'s
membranes
Solution
As per the given options rough endoplasmic reticulum functions are :-
2) Absorbtion, synthesis and transport of fats & 4) Synthesis of cell membranes
Generally, the eucaryotic cell contains two types of endoplasmic reticulum
i) Rough Endoplasmic Reticulum.
Rough Endoplasmic Reticulum why named as rough means it contains ribosomes on it so, the
surface of the reticulum looks rough. The main function of the rough ER is protein synthesis due
to the ribosomes.
Rough ER through the membrane contact sites contact with the other organells allowing the
transfer of lipids and other small molecules.
The intestinal cells, pancreatic cells, which involves in the absorption process contains more
rough ER why because the proteins synthesized by the Rough ER involved in the intracellular
transport of resynthesized lipids.So the rough ER indirectly helps in the absorption process.
ii)Smooth Endoplasmic Reticulum:-
Due to the absence of ribosomes it looks smooth so named as smooth ER. The main role is lipid
metabolism, and synthesis of carbohydrates and steroid harmones and storage of calcium ions
So, in the given question the first option(Lipid metabolism, cholesterol synthesis, synthesis of
lipid components of lipo proteins) indicates smooth Endoplasmic Reticulum functions
2nd option Absorbtion, synthesis and transport of fats indicates Rough Endoplasmic Reticulum
functions
3rd Option Indicates(Storage of Calcium ions) smooth Endoplasmic Reticulum functions
4th Option is synthesis of cell membrane, For this function the main role of rough Endoplasmic
reticulum is during the lipid transport the replenishment of new membranes is done by the
morphological change of rough endoplasmic reticulum involved..

What is isomerism? How many kinds are there? Define each kind and explain with examples?
Solution
The process of isomerism involves the isomers .These are basically defined as the molecules
which have the same molecular formula but they usually possess a different arrangement of the
atoms in space. They are of two types:
1.Constitutional isomers :They are defined as the compounds in which the various atoms are
connected or bonded in a different manner .They are also called as structural isomers
2.Stereoisomers:On the other hand ,they are the compounds which differ on the basis of
orientation in space.They are of two types
a)Enantiomers :They are the compounds which are usually a mirror image of one another and
thehese mirror images are also non-superimposable
b)Diastereomers :They are isomers which are not mirror images of one another.Moreover these
compounds are non-superimposable. They are of two types: cis and trans
->Cis-isomers are the isomers which usually contain atoms which are oriented on the same side
of a bond.
->On the other hand the Trans-isomers are the compounds that have atoms oriented on opposite
sides of a bond.

4- Counter
5- Adder
6- Multiplexer
Solution
1. The D flip-flop tracks the input, making transitions with match those of the input D. The D
stands for \"data\"; this flip-flop stores the value that is on the data line. It can be thought of as a
basic memory cell. The Q output always takes on the state of the D input at the moment of a
rising clock edge. (or falling edge if the clock input is active low).
2. A register is a group of binary cells suitable for holding binary information. A group of
cascaded flip flops used to store related bits of information is known as a register.
4. A counter is a device which stores (and sometimes displays) the number of times a particular
event or process has occurred, often in relationship to a clock signal. Each pulse applied to the
clock input increments or decrements the number in the counter.
5. An adder, also called summer, is a digital circuit that performs addition of n-bit binary
numbers.
6. A multiplexer (or mux) is a device that selects one of several analog or digital input signals
and forwards the selected input into a single line. A multiplexer of 2n inputs has n select lines,
which are used to select which input line to send to the output..
Two sources of radio waves (call them 1 and 2) are separated by a dis.pdf
Two sources of radio waves (call them 1 and 2) are separated by a distance d along the a-axis in
the plane, and emit sinusoidal waves of the same wavelength A and frequency f in the N (+y), S
(-y), E (+x), and W (-x) directions. Suppose that we want to arrange the sources to broadcast a
signal in the E direction, but not the W. Can this be accomplished? If so, how? In not, why?
Solution
both the sources are identicle and emit in all direction N,S,E,W. by introducing a path difference
equal to half wave length the waves will have distructive interference and signal is destroyed but
this happens in both the direction E nd W equally.
Hence it is not possible to arrnge the sources such that we have signal only in E nd not in W, the
only way to achieve this is to shield the source in W direction or put reflectors in W direction so
that all W signal is reflected back to E.

TB is a major worldwide disease with new cases arising at an alarmin.pdf
TB is a major worldwide disease with new cases arising at an alarming rate, What factors can
account for this and what lays behind the trend of multidrug resistant strains of mycobacterium?
please cite reference.
Solution
Tuberculosis is caused by mycobacteriam tuberculosis. TB is one of the most common cause of
death due to infection of the mycobacteriam species.various factor have been found to develop
resistance against M. tuberculosis. resistance means simply afterwards that drug potency in terms
of pharmacological response will be decresed gradually and at certain level it will not active
against the strain. There are two types of resistance 1. natural resistance and second is aquired
resistance. natural resistance is found on wild strain. multidrug resistance is the phase in which
strain is not responsive against primary line therapy of disease.
factor which induced resistance
gene factor
In a recent year study suggest that the patient who shows the presence of HLA -DRB1 13 and
HLA-DRB 1 14 has two fold risk to develop resistance against strain.(Park et al.)
Incomplete and inadequate mangment Review of literature suggests that the most powerful
factor of MDR-TB is a history of treatment of tuberculosis(diagnosis). TB patients get treated
with DOTS regimens not only through the Revised National Tuberculosis Control Programme
(RNTCP), but also receive treatment from private medical doctors. Irregular, incomplete,
inadequate treatment is the commonest mean of acquiring drug resistant due to improper
mangment of drug mostly organism develop the resistnacce against drug eg. use of single drug to
treat tb is the fetal cause to develope resistance against organisms.it may be due to ignorance.
anothe common error in prescription error it may like additions syndromes.
Inadequate treatment compliance : the change over form has complied a significant effece in
development of drug resistance it was observed that only 44 per cent of the patients receiving
short-course treatment (n=2300) and 36 per cent of those receiving standard chemotherapy
(n=1000) completed 81 per cent or more of their treatment.
Noncompliance with prescribed treatment is often underestimated by the physician and is
difficult to predict. On the other hand, certain factors such as psychiatric illness, alcoholism, drug
addiction and homelessness do predict noncompliance .The drug defaulter, just like placebo
reactor is not a consistent or readily identified person demographic factors such as ,sex, age,
marital status,socio-economic status and education levelhave not been found to correlate with the
degree of compliance..

Solution
7. How did printing technology impact literacy and education?
Printing technology impacted literacy and education. Printing transformend the world and made
very important changes.
Previously people don\'t have much access to information. They used to write. So, the books are
expensive. In 15th century Johannes Gutenberg invented a printing machine and made it
available to world.
Not all are rich enough to buy hand written books till 15th century. As books are expensive so
does literacy. To learn to read and write, need to refer to books. When this printing machine
came to availability, books became cheap and affordable. Then on wards the barrier of high cost
had gone.
Source of knowledge are hand written papers or books besides people. Information is not so
much available. Again because of expensive things. When printing is available news papers
came into picture and from then on people had one more source of knowledge which is cheaper.
In this way printing technology impact literacy and education..

A geneticist Dr. O. Sophila discovers a new mutation that causes the .pdf
A geneticist Dr. O. Sophila discovers a new mutation that causes the flies to shake and quiver.
She calls this mutation spastic (sps) and determines that spastic is due to an autosomal recessive
mutation. She wants to determine if the spastic gene is linked to the gene for vestigial wings (vg)
- also a recessive phenotype. She has true breeding stocks for each kind of mutations. She
crosses a spastic fly with a vestigial wing fly and then uses the resulting F1 females in a
testcross. She obtains the following F2 flies from the testcross: Spastic with normal wings 230
NonSpastic with vestigial wings 224 Spastic with vestigial wings 97 NonSpastic with normal
wings 99 Are the genes that cause vestigial wings and the spastic mutation linked? Provide the
rationale to your answer. What is the genotype and phenotype of F1 females? Annotate the
genotype notation illustrates whether sps and vg alleles are in cis or trans arrangement to each
other. What is(are) phenotype(s) of th
Solution
Answer:
3.1)
Spastic (recessive) = s; Nonspastic (dominant)=s+
Vestigial wings (recessive)= v; Normal wings(dominant) = V
ssVV (spastic fly) x s+ s+ vv (Vestigial wings)-----P
sV s+v----------------------------gametes
s+sVv (nonspastic, normal wing)---------F1
F1 X ssvv------------Test cross.
During test cross, all the progeny should be in equal proportion, but it is not the case. So the
genes were linked.
3.2).
F1 phenotype= nonspastic, normal wing
Genotyope: s+sVv
Recessive allele of one gene and dominant allele of the other gene present on the same
chromosome, so the configuration of the genes is trans configuration.
3.3).
The recombinant phenotypes of F2 files are= spastic with vestigial wings and nonspastic with
normal wings
3.4).
spastic with normal wings = ss Vv
Nonspastic with vestigial wings = s+svv
Spastic with vestigial wings = ssvv
Nonspastic with normal wings= s+sVv
3.5).
%Recombinant frequency = map distance (map units)
Recombinat frequency = (total number of recombinants / Total progeny)100
= 97+99 = (196/650)100 = 30.15%
The genetic distance between the v and s genes is 30.15 map units.
o Dfe the cefcien of hermal expansion. What is the relation between t.pdf
o Dfe the cefcien of hermal expansion. What is the relation between the linear and the
volumetric coefficients of thermal expansion?
Solution
is the ratio of the fractional change in size of a material to its change in temperature; is
represented by the symbol (alpha) for solids and (beta) for liquids.
relation between linear and volumetric coefficients of thermal expansion is that V=3L
Where, V = volumetric coefficients of thermal expansion
L = linear coefficients of thermal expansion.
Monohybrid crosses with incomplete dominance and co-dominance The red.pdf
Monohybrid crosses with incomplete dominance and co-dominance The red and white alleles
for the snapdragon flower color gene exhibit incomplete dominance. When pink flowers were
produced from red- and white-flowered parents, early geneticists thought this might represent
\"blending inheritance, \" where the hereditary information from one parent melded with the
information from the other. Use Punnett Squares to determine the phenotype ratios in snapdragon
offspring from the following crosses, that show that blending inheritance is not an accurate way
to characterize this situation. define the notation (letters) you will use: pink x pink (if blending
inheritance were accurate, we would predict that all offspring would be pink) pink x red (if
blending inheritance were accurate, we would predict that all offspring would be dark pink)
Solution
A cross between pink and pink flower plants.
The genotype of pink flower plants would be Rr (R allele for red colour and r allele for white
colour). A case of incomplete dominance.
The gamete formation results in R and r genotypes
And the offsprings will be red ,pink, white in the ratio of 1:2:1 respectively.
All offsprings are not pink. There is segregation of alleles during gamete formation, that results
in new combination of genes in tha offsprings. Here alleles for red and white colour were present
in the parents and their offsprings also contains new combination of alleles.
A cross between red and pink flower plants.
The genotype red is RR and pink is Rr. The cross between the two results in red and pink flowere
in equal ratio 2:2.
Here the alleles were present for red and white colour in the parents RR X Rr.
There is no occurance of blending inheritance, Here the concerned genes for red (RR) and white
(rr) colour show incompletee dominance when come together in an organism and shows pink
colour (Rr). This does not mean that it happens in all conditions, as the conditions are
exceptional cases. Here the heterozygote (Rr) posses genes for both red and white colour and
when self crossed results in new combination of genes due to their segregation during gamete
formation and homozygous condition will be retained in some plants (RR and rr) that results in
red and white flowers.RrRRRRrrRrrr.

Jumbo shrimp are those that require 10 to 15 shrimp to make a pound..pdf
Jumbo shrimp are those that require 10 to 15 shrimp to make a pound. Suppose that the number
of jumbo shrimp in a 1-pound bag averages ? = 12.5 with a standard deviation of ? =1, and forms
a normal distribution. What is the probability of randomly picking a sample on n=25 1-pound
bags that average more than M=13 shrimp per bag?
Solution
P(xbar>13) = P((xbar-mean)/(s/vn) >(13-12.5)/(1/5))
=P(Z>2.5) = 0.0062 (from standard normal table).
In metaphase 1 of meiosis, the homologous chromosomes line up side by.pdf
In metaphase 1 of meiosis, the homologous chromosomes line up side by side along the equator
so that (a) crossing-over (exchange of DNA regions) can occur between the homologous pairs
and (b) the homologous chromosomes can be pulled to opposite poles during anaphase 1. In
mitosis, by contrast, homologous chromosomes line up single-file along the equator. What
benefits are derived from these two different ways that homologous chromosomes are positioned
at metaphase in meiosis and mitosis?
Solution
The equatorial arrangement of chromosomes make the cell divisions to occur more
symmetrically. This chromosomal alignment is the keyspot of metazoan cell divisions. The
spindle fibers in both mitosis and meiosis relocate the metaphase plates if they are not properly
arranged. Homologous chromosomes functions differently in both mitosis and meiosis. The
homologous chromosomes in mitosis do not pair with eachother like they do in meiosis. They
line up independently at the equatorial plate whereas in meiosis they occur in pairs. The chances
of chromosomes to cross one another by mitotic recombination is very rare..
Implement the sequence class from Section 3.2 of the textbook. The d.pdf
Implement the sequence class from Section 3.2 of the textbook. The documentation and
definition portion of this sequence ADT is provided in textbook (pp.124-133), and is posted in
BlackBoard of this class too.
Also implement two operators + and += for the ADT. For the + operator, x+y (a new sequence)
contains all the items of x, followed by all the items of Y.
The statement x += y appends all of the items of y to the end of what’s already in X.
For simplicity, let’s assume the sequence contains integer items and the capacity is 30.
Write a simple application to manage a playlist of your favorite music, where the sequence class
is used to insert, delete, search and print the title of music.
Your application should read in integral numbers (an ID, instead of title, for simplicity) of each
piece of music and insert them onto a sequence. It should be able to insert an item at a specified
location, find and display the music currently at play, delete a specified item from the sequence
as well as display the entire list of music in the sequence.

Gene frequencies for the ABO alleles vary geographically. For exa.pdf
Gene frequencies for the ABO alleles vary geographically. For example the I^A allele makes up
nearly 50% of the genes for blood type among Australian Aborigines, about 25% in Central
Asian populations, and 0% in peoples native to South America. No blood type has sufficient
selective advantage over another to explain these regional differences. From these facts, what
can you infer about the history of our species Did humanity develop as a large and continuous
population spreading out across the planet, or did we disperse while still living in small scattered
groups
Solution
Based on the above data human population developed as small, some of them scattered into
small groups and acclimatised to new geographical area. In each group some dominant blood
alleles become predominant and become major allele in that population during course of time.
This is the reason for differences in gene frequencies.

Explain the factors that determine the binding specificity between the enzyme and substrate?
Solution
(1) the substrate should be specific to the enzymes active binding site..
(2) the substrate and the enzymes should be able to undergo the needful confitmational changes
for for proper binding..
(3) the binding should be no-covalent in nature so that the substrate should easily be removed
after the process done to allow the enzymes to bind the other substrate..
(4) the Km value of the enzymes should be less to allow the binding at a lower substrate
concentration too...

What is isomerism? How many kinds are there? Define each kind and explain with examples?
Solution
The process of isomerism involves the isomers .These are basically defined as the molecules
which have the same molecular formula but they usually possess a different arrangement of the
atoms in space. They are of two types:
1.Constitutional isomers :They are defined as the compounds in which the various atoms are
connected or bonded in a different manner .They are also called as structural isomers
2.Stereoisomers:On the other hand ,they are the compounds which differ on the basis of
orientation in space.They are of two types
a)Enantiomers :They are the compounds which are usually a mirror image of one another and
thehese mirror images are also non-superimposable
b)Diastereomers :They are isomers which are not mirror images of one another.Moreover these
compounds are non-superimposable. They are of two types: cis and trans
->Cis-isomers are the isomers which usually contain atoms which are oriented on the same side
of a bond.
->On the other hand the Trans-isomers are the compounds that have atoms oriented on opposite
sides of a bond.

What is the definition of the words, and state the difference between them if there is:
1- D-Flip Flop
2- Register
3- Equality
4- Counter
5- Adder
6- Multiplexer
Solution
1. The D flip-flop tracks the input, making transitions with match those of the input D. The D
stands for \"data\"; this flip-flop stores the value that is on the data line. It can be thought of as a
basic memory cell. The Q output always takes on the state of the D input at the moment of a
rising clock edge. (or falling edge if the clock input is active low).
2. A register is a group of binary cells suitable for holding binary information. A group of
cascaded flip flops used to store related bits of information is known as a register.
4. A counter is a device which stores (and sometimes displays) the number of times a particular
event or process has occurred, often in relationship to a clock signal. Each pulse applied to the
clock input increments or decrements the number in the counter.
5. An adder, also called summer, is a digital circuit that performs addition of n-bit binary
numbers.
6. A multiplexer (or mux) is a device that selects one of several analog or digital input signals
and forwards the selected input into a single line. A multiplexer of 2n inputs has n select lines,
which are used to select which input line to send to the output..
Two sources of radio waves (call them 1 and 2) are separated by a dis.pdf
Two sources of radio waves (call them 1 and 2) are separated by a distance d along the a-axis in
the plane, and emit sinusoidal waves of the same wavelength A and frequency f in the N (+y), S
(-y), E (+x), and W (-x) directions. Suppose that we want to arrange the sources to broadcast a
signal in the E direction, but not the W. Can this be accomplished? If so, how? In not, why?
Solution
both the sources are identicle and emit in all direction N,S,E,W. by introducing a path difference
equal to half wave length the waves will have distructive interference and signal is destroyed but
this happens in both the direction E nd W equally.
Hence it is not possible to arrnge the sources such that we have signal only in E nd not in W, the
only way to achieve this is to shield the source in W direction or put reflectors in W direction so
that all W signal is reflected back to E.

TB is a major worldwide disease with new cases arising at an alarmin.pdf
TB is a major worldwide disease with new cases arising at an alarming rate, What factors can
account for this and what lays behind the trend of multidrug resistant strains of mycobacterium?
please cite reference.
Solution
Tuberculosis is caused by mycobacteriam tuberculosis. TB is one of the most common cause of
death due to infection of the mycobacteriam species.various factor have been found to develop
resistance against M. tuberculosis. resistance means simply afterwards that drug potency in terms
of pharmacological response will be decresed gradually and at certain level it will not active
against the strain. There are two types of resistance 1. natural resistance and second is aquired
resistance. natural resistance is found on wild strain. multidrug resistance is the phase in which
strain is not responsive against primary line therapy of disease.
factor which induced resistance
gene factor
In a recent year study suggest that the patient who shows the presence of HLA -DRB1 13 and
HLA-DRB 1 14 has two fold risk to develop resistance against strain.(Park et al.)
Incomplete and inadequate mangment Review of literature suggests that the most powerful
factor of MDR-TB is a history of treatment of tuberculosis(diagnosis). TB patients get treated
with DOTS regimens not only through the Revised National Tuberculosis Control Programme
(RNTCP), but also receive treatment from private medical doctors. Irregular, incomplete,
inadequate treatment is the commonest mean of acquiring drug resistant due to improper
mangment of drug mostly organism develop the resistnacce against drug eg. use of single drug to
treat tb is the fetal cause to develope resistance against organisms.it may be due to ignorance.
anothe common error in prescription error it may like additions syndromes.
Inadequate treatment compliance : the change over form has complied a significant effece in
development of drug resistance it was observed that only 44 per cent of the patients receiving
short-course treatment (n=2300) and 36 per cent of those receiving standard chemotherapy
(n=1000) completed 81 per cent or more of their treatment.
Noncompliance with prescribed treatment is often underestimated by the physician and is
difficult to predict. On the other hand, certain factors such as psychiatric illness, alcoholism, drug
addiction and homelessness do predict noncompliance .The drug defaulter, just like placebo
reactor is not a consistent or readily identified person demographic factors such as ,sex, age,
marital status,socio-economic status and education levelhave not been found to correlate with the
degree of compliance..

7. How did printing technology impact literacy and education?
Solution
7. How did printing technology impact literacy and education?
Printing technology impacted literacy and education. Printing transformend the world and made
very important changes.
Previously people don\'t have much access to information. They used to write. So, the books are
expensive. In 15th century Johannes Gutenberg invented a printing machine and made it
available to world.
Not all are rich enough to buy hand written books till 15th century. As books are expensive so
does literacy. To learn to read and write, need to refer to books. When this printing machine
came to availability, books became cheap and affordable. Then on wards the barrier of high cost
had gone.
Source of knowledge are hand written papers or books besides people. Information is not so
much available. Again because of expensive things. When printing is available news papers
came into picture and from then on people had one more source of knowledge which is cheaper.
In this way printing technology impact literacy and education..

Q Describe the 2 types of homologs. (1) Orthologs (2) ParalogsS.pdf
Q: Describe the 2 types of homologs. (1) Orthologs (2) Paralogs
Solution
1. Orthologs: These are genes found in different species that resulted from speciation of a
common ancestral gene. During this event of evolution, the orthologs retain their original
function.
2. Paralogs: These genes are resulted from duplication event with a genome. And during the
evolution, paralogs evolve to attain new function unlike orthologs..

A geneticist Dr. O. Sophila discovers a new mutation that causes the .pdf
A geneticist Dr. O. Sophila discovers a new mutation that causes the flies to shake and quiver.
She calls this mutation spastic (sps) and determines that spastic is due to an autosomal recessive
mutation. She wants to determine if the spastic gene is linked to the gene for vestigial wings (vg)
- also a recessive phenotype. She has true breeding stocks for each kind of mutations. She
crosses a spastic fly with a vestigial wing fly and then uses the resulting F1 females in a
testcross. She obtains the following F2 flies from the testcross: Spastic with normal wings 230
NonSpastic with vestigial wings 224 Spastic with vestigial wings 97 NonSpastic with normal
wings 99 Are the genes that cause vestigial wings and the spastic mutation linked? Provide the
rationale to your answer. What is the genotype and phenotype of F1 females? Annotate the
genotype notation illustrates whether sps and vg alleles are in cis or trans arrangement to each
other. What is(are) phenotype(s) of th
Solution
Answer:
3.1)
Spastic (recessive) = s; Nonspastic (dominant)=s+
Vestigial wings (recessive)= v; Normal wings(dominant) = V
ssVV (spastic fly) x s+ s+ vv (Vestigial wings)-----P
sV s+v----------------------------gametes
s+sVv (nonspastic, normal wing)---------F1
F1 X ssvv------------Test cross.
During test cross, all the progeny should be in equal proportion, but it is not the case. So the
genes were linked.
3.2).
F1 phenotype= nonspastic, normal wing
Genotyope: s+sVv
Recessive allele of one gene and dominant allele of the other gene present on the same
chromosome, so the configuration of the genes is trans configuration.
3.3).
The recombinant phenotypes of F2 files are= spastic with vestigial wings and nonspastic with
normal wings
3.4).
spastic with normal wings = ss Vv
Nonspastic with vestigial wings = s+svv
Spastic with vestigial wings = ssvv
Nonspastic with normal wings= s+sVv
3.5).
%Recombinant frequency = map distance (map units)
Recombinat frequency = (total number of recombinants / Total progeny)100
= 97+99 = (196/650)100 = 30.15%
The genetic distance between the v and s genes is 30.15 map units.
o Dfe the cefcien of hermal expansion. What is the relation between t.pdf
o Dfe the cefcien of hermal expansion. What is the relation between the linear and the
volumetric coefficients of thermal expansion?
Solution
is the ratio of the fractional change in size of a material to its change in temperature; is
represented by the symbol (alpha) for solids and (beta) for liquids.
relation between linear and volumetric coefficients of thermal expansion is that V=3L
Where, V = volumetric coefficients of thermal expansion
L = linear coefficients of thermal expansion.
Monohybrid crosses with incomplete dominance and co-dominance The red.pdf
Monohybrid crosses with incomplete dominance and co-dominance The red and white alleles
for the snapdragon flower color gene exhibit incomplete dominance. When pink flowers were
produced from red- and white-flowered parents, early geneticists thought this might represent
\"blending inheritance, \" where the hereditary information from one parent melded with the
information from the other. Use Punnett Squares to determine the phenotype ratios in snapdragon
offspring from the following crosses, that show that blending inheritance is not an accurate way
to characterize this situation. define the notation (letters) you will use: pink x pink (if blending
inheritance were accurate, we would predict that all offspring would be pink) pink x red (if
blending inheritance were accurate, we would predict that all offspring would be dark pink)
Solution
A cross between pink and pink flower plants.
The genotype of pink flower plants would be Rr (R allele for red colour and r allele for white
colour). A case of incomplete dominance.
The gamete formation results in R and r genotypes
And the offsprings will be red ,pink, white in the ratio of 1:2:1 respectively.
All offsprings are not pink. There is segregation of alleles during gamete formation, that results
in new combination of genes in tha offsprings. Here alleles for red and white colour were present
in the parents and their offsprings also contains new combination of alleles.
A cross between red and pink flower plants.
The genotype red is RR and pink is Rr. The cross between the two results in red and pink flowere
in equal ratio 2:2.
Here the alleles were present for red and white colour in the parents RR X Rr.
There is no occurance of blending inheritance, Here the concerned genes for red (RR) and white
(rr) colour show incompletee dominance when come together in an organism and shows pink
colour (Rr). This does not mean that it happens in all conditions, as the conditions are
exceptional cases. Here the heterozygote (Rr) posses genes for both red and white colour and
when self crossed results in new combination of genes due to their segregation during gamete
formation and homozygous condition will be retained in some plants (RR and rr) that results in
red and white flowers.RrRRRRrrRrrr.

Jumbo shrimp are those that require 10 to 15 shrimp to make a pound..pdf
Jumbo shrimp are those that require 10 to 15 shrimp to make a pound. Suppose that the number
of jumbo shrimp in a 1-pound bag averages ? = 12.5 with a standard deviation of ? =1, and forms
a normal distribution. What is the probability of randomly picking a sample on n=25 1-pound
bags that average more than M=13 shrimp per bag?
Solution
P(xbar>13) = P((xbar-mean)/(s/vn) >(13-12.5)/(1/5))
=P(Z>2.5) = 0.0062 (from standard normal table).
In metaphase 1 of meiosis, the homologous chromosomes line up side by.pdf
In metaphase 1 of meiosis, the homologous chromosomes line up side by side along the equator
so that (a) crossing-over (exchange of DNA regions) can occur between the homologous pairs
and (b) the homologous chromosomes can be pulled to opposite poles during anaphase 1. In
mitosis, by contrast, homologous chromosomes line up single-file along the equator. What
benefits are derived from these two different ways that homologous chromosomes are positioned
at metaphase in meiosis and mitosis?
Solution
The equatorial arrangement of chromosomes make the cell divisions to occur more
symmetrically. This chromosomal alignment is the keyspot of metazoan cell divisions. The
spindle fibers in both mitosis and meiosis relocate the metaphase plates if they are not properly
arranged. Homologous chromosomes functions differently in both mitosis and meiosis. The
homologous chromosomes in mitosis do not pair with eachother like they do in meiosis. They
line up independently at the equatorial plate whereas in meiosis they occur in pairs. The chances
of chromosomes to cross one another by mitotic recombination is very rare..
Implement the sequence class from Section 3.2 of the textbook. The d.pdf
Implement the sequence class from Section 3.2 of the textbook. The documentation and
definition portion of this sequence ADT is provided in textbook (pp.124-133), and is posted in
BlackBoard of this class too.
Also implement two operators + and += for the ADT. For the + operator, x+y (a new sequence)
contains all the items of x, followed by all the items of Y.
The statement x += y appends all of the items of y to the end of what’s already in X.
For simplicity, let’s assume the sequence contains integer items and the capacity is 30.
Write a simple application to manage a playlist of your favorite music, where the sequence class
is used to insert, delete, search and print the title of music.
Your application should read in integral numbers (an ID, instead of title, for simplicity) of each
piece of music and insert them onto a sequence. It should be able to insert an item at a specified
location, find and display the music currently at play, delete a specified item from the sequence
as well as display the entire list of music in the sequence.
// FILE: sequence1.h

//
// typedef ____ size_type
// sequence::size_type is the data type of any variable that keeps track of
// how many items are in a sequence.
//
// static const size_type CAPACITY = _____

// Postcondition: The first item on the sequence becomes the current item
// (but if the sequence is empty, then there is no current item).
//
// void advance( )
// Precondition: is_item returns true.
// Postcondition: If the current item was already the last item in the

Gene frequencies for the ABO alleles vary geographically. For exa.pdf
Gene frequencies for the ABO alleles vary geographically. For example the I^A allele makes up
nearly 50% of the genes for blood type among Australian Aborigines, about 25% in Central
Asian populations, and 0% in peoples native to South America. No blood type has sufficient
selective advantage over another to explain these regional differences. From these facts, what
can you infer about the history of our species Did humanity develop as a large and continuous
population spreading out across the planet, or did we disperse while still living in small scattered
groups
Solution
Based on the above data human population developed as small, some of them scattered into
small groups and acclimatised to new geographical area. In each group some dominant blood
alleles become predominant and become major allele in that population during course of time.
This is the reason for differences in gene frequencies.
Explain the factors that determine the binding specificity between t.pdf
Explain the factors that determine the binding specificity between the enzyme and substrate?
Solution
(1) the substrate should be specific to the enzymes active binding site..
(2) the substrate and the enzymes should be able to undergo the needful confitmational changes
for for proper binding..
(3) the binding should be no-covalent in nature so that the substrate should easily be removed
after the process done to allow the enzymes to bind the other substrate..
(4) the Km value of the enzymes should be less to allow the binding at a lower substrate
concentration too...

Write a class called Student that extends the provided Person class..pdf
- 1. Write a class called Student that extends the provided Person class. Ensure that your student class is a concrete class. The foo method for a person should display (to standard output) the person's age and name in a nice way (e.g, "Nigel's age is 14"). When a person makes a noise it is their name repeated N times where N is the person's age. public abstract class Person implements Noisy Person Class public String name; 3 ublic int age; s public abstract void foo); public interface Noisy 2 String noise) 1 public interface Noisy{ Noisy Interface 1 public interface Comparable 2 i Comparable Interface int compareTo(Type other); 1 public class Date 2 int day, month, year; Date Class public Date(int d, int m, int y){ dayd; month - m; year-y; Solution public class Student extends Person{ Student(String name, int age){ this.name = name; // initialising the student properties this.age = age; } public void foo(){ if(isNoisy()){ //check if person makes noise for(int i=0 ; i< age; i++ ){ System.out.print(" "+name+" "); } }else{ System.out.println(name+"'s age is "+age); } } } // Note: Information about the Noisy class is required.
