Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.

- Experiment: Bradford protein assaygive the answers (4-5 lines) of review questions in the end. answer should be logical and understandable and without plagiarism. avoid copy pasting. Background information:The Bradford assay is very fast and uses about the same amount of protein as the Lowry assay. It is fairly accurate and samples that are out of range can be retested within minutes. The Bradford is recommended for general use, especially for determining protein content of cell fractions and assessing protein concentrations for gel electrophoresis. The method described below is for a 100 µl sample volume using 5 ml color reagent. It is sensitive to about 5 to 200 micrograms protein, depending on the dye quality. In assays using 5 ml color reagent prepared in lab, the sensitive range is closer to 5 to 100 µg protein. Scale down the volume for the "micro assay procedure," which uses 1 ml cuvettes. Protocols, including use of microliter plates are described in the flyer that comes with…INSTRUCTION: = IF BOTH STATEMENT ARE TRUE = IF FIRST STATEMENT IS TRUE WHILE SECOND STATEMENT IS FALSE = IF FIRST STATEMENT IS FALSE WHILE SECOND STATEMENT IS TRUE = IF BOTH STATEMENTS ARE FALSE STAMENT 1: Amino acyl tRNA synthase is the enzyme responsible for joining amino acid together STAMENT 2: Nucleus is the part of the cell where translation takes place ANSWER: STAMENT 1: DNA sequences where RNA polymerase binds initially is called promoter sequences STAMENT 2: UV light causes adenine to dimerize ANSWER: STAMENT 1: Guanosine is the name of the compound formed when guanine is bonded to ribose STAMENT 2: DNA pairing is the term that refers to the process when two complementary and single stranded DNA combine ANSWER:Genetics problem part 1.

- Complete the following problems. 1. Draw a molecule of phosphatidyl serine using palmitic acid and linoleic (Δ9,12) acid 2. Consider the following coding strand sequence of DNA to a corresponding amino acid sequence. This represents the first amino acids to be translated. Underline the codon where translation will be initiated, and give the amino acid sequence of the peptide produced. 5’-CGATGCTCAAGTTTC-3’ 3. Within the matrix of the mitochondria, the pH is approximately 6.8 ([H+] = 1.6 X 10-7), while it is 7.4 ([H+] = 4.0 X 10-8) in the intermembrane space outside the matrix. Calculate the free energy driving transport of hydrogen ions from the intermembrane space to the matrix. Remember to include both the concentration and the membrane potential factors. 4. Draw the adenosine-5’-diphosphate.MRNA- based therapeutics The following questions: Which research group has initially developed the technology? What was the purpose behind the invention of the technology? What type of questions could be answered with the technology? What are the applications of the technology? Are there any clinical trials associated with the method? What is the mechanism of action for the technology?Drug 2-Lumacaftor (VX-809): In people with the most common CF mutation, F508del, a series of problems prevents the CFTR protein from folding into the correct shape and reaching its proper place on the cell surface. The cell recognizes the protein as abnormal and targets it for degradation before it makes it to the cell surface. In order to treat this problem, two drugs are required - an agent to get the protein to the surface and then Ivacaftor to open the channel and increase chloride transport. The drug Lumacaftor has been identified as a treatment to help with the trafficking of the protein to the cell surface. When Lumacaftor is added to Ivacaftor, the protein gets to the surface and also increases chloride transport by increasing channel opening time. For which class(es) of mutations would Lumacaftor be most effective?

The problem is: Ribosoms were isolated from bacteria grown in a "heavy" medium (13C and 15N) and from bacteria grown in "light" medium (12C and 14N). These 70S ribosoms were added to an in vitro system engaged in protein synthesis. An aliquot removal serveral hours later was analyzed by density-gradient centrifugation. How many bands of 70S ribosoms would you expect to see in the density gradient? Is it possible to give a more comprehensive explanation? :) Expert Solution Step 1 Introduction :- A ribosome is a sophisticated molecular machine that produces proteins from amino acids during the process of protein synthesis, also known as translation.
