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..

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? 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 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 Concentration in sediment sample of Concentration in Concentration in reference bulk HRS bulk marina sediment to be sediment sample sediment sample dredged Bulk Standard sediment elutriate (mg/kg)(mg/L) (mg/kg) (mg/kg) 13 0.02 Barium Cyanide Iron Mercury Dieldrin p.p\'- DDE Chlorobenzene 16 65 0.70 13,000 120 14 53 0.40 12,500 130 0.60 11,000 100 0.02 3x10-7 8x10 1.3x10 0.32 0.008 0.0034 0.12 1.3 38,000 Total organic 21,000 10,300 carbon (TOC) a.

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 crystals to different angles and position of the elactase crystal.Researchers likely rotated elactase crystals to different angles to understand to confirmation of this enzyme from all sides..

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. 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. 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..

Drug release profile of acetaminophen (APAP) in cellulose excipient was observed by dissolving the tablet in the saturated solution of APAP. If the initial porosity of the tablet before dissolution is 2%, diffusion constants of excipient and APAP are 0.3 and 0.5, ?u=?v=1.5 and Solution 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.
