For each of the mutations below, which mutation is more likely to disrupt the structure of a protein (that is, make a mutant protein that is less stable than the nonmutant protein)? In each case, explain your reasoning.
A. A mutation which changes a Lys (nonmutant protein, called the "wild type" protein ) to a Gln (mutant protein) or one which changes a Leu (wild type protein) to a Gln (mutant protein).
B. A mutation which changes a Phe (wild type protein) to a Gly (mutant protein) or one which changes a Phe (wild type protein) to a Leu (mutant protein).
C. A mutation which changes a Pro (wild type protein) to a Gly (mutant protein) or one which changes a Gly (wild type protein) to a Pro (mutant protein).
Suppose if insulin were treated with mercaptoethanol to break its disulfide bonds, and then the mecaptoethanol were removed so that disulfide bonds could reform,
You perform a forward genetic screen to look for Arabidopsis thaliana mutants that are altered in cold stress responses. You find two mutants with opposite phenotypes.
From a bacteria stock you serially dilute 1/100 two times, then serially dilute 1/10 two times. From this last tube you plate 100 ul, which produces 156 colonies the other day.
Determine when glucagon binds its receptor there is an increase in the second messenger, cAMP. cAMP levels can be reduce by which of the following enzymes?
Use the South University Online Library or the Internet, examine about brainstem, diencephalon, cerebellum, and cerebrum.
Tanzanian mudguppies have either green or purple skin. Assume you are interested in the inheritance of skin color in the mudguppie.
A genomic library is made for a haploid organis with a genome of 3 X 10^9 bp. If you want to clone five genome equivalent into a vector library.
Assuming that the virus capsid is spherical, work with your classmates to calculate what is the maximum genome size (in nucleotides) that can fit into the capsid. How long in millimeters would this largest possible RNA genome be?
though , the addition of a trace of uniformly labeled [14C]acetyl-CoA in the presence of an excess of unlabeled malonyl-CoA to a soluble liver fraction yields palmitate labeled with 14C only in C-15 and C-16.
Question What causes cancer? Why is finding a cure so difficult? Why do certain drugs work for some people but not others?
Determine how much in mL of .5 M NaOH total can you add to the solution in question 4 and still have a good buffer also Extimate the pH of a 0.05 M solution of TRIS acid (pKa=8.3)?
Codons with U or C as the second nucleotide, for example, tend to specify hydrophobic amino acids. Can you recommend a possible explanation for this phenomenon in terms of the early evolution of the protein synthesis machinery?
