See the hypothetical pathway answer the following questions.
A) If an individual is homozygous for a null mutation in the gene that codes for Enz1, what would the result be?
B) What would happen if an individual is heterozygous for a mutation that abolishes the activity of Enz2?
C) What could happen to the offspring of the individuals described above (in a and b)? Assume that they only have the mutations described.
In our feeding experiment with vermilion/brown and cinnabar/brown mutant flies, we were supposed to use kynurenine or hydroxykynurenine to overcome the enzymatic block in the ommochrome pathway, caused by the vermilion or cinnabar mutations. Which eye color would you expect for each of the two double mutants, if we had supplemented the medium with N-formylkynurenine? Use a diagram of the pathway to explain your answer.
Mabelle used the pET vector system to express her prokaryotic amylase enzyme. She added
IPTG into her culture broth of DH5a Escherichia coli strain. At the end of the experiment,
she discovered that her protein was not expressed. She repeated three more times but her
protein of interest was still not produced.
(i)
(ii)
Explain the reason why Mabelle failed to obtain her protein of interest and suggest a
solution to troubleshoot this problem.
Mabelle plans to express her protein fused to a polyhistidine-tag (His-tag). Explain
the importance of His-tag in protein work.

- What is an exconjugant? How do you think that exconjugants were obtained? (It might include genes not described in this problem.)arrow_forwardIn DNA-hybridization experiments on six species of plants in the genus Vicia, DNA was isolated from each of the six species, denatured by heating, and sheared into small fragments (W. Y. Chooi. 1971. Genetics 68:213–230). In one experiment, DNA from each species and from E. coli was allowed to renature. The graph shows the results of this renaturation experiment. Q. Notice that, for the Vicia species, the rate of renaturation is much faster in the first hour and then slows down. What might cause this initial rapid renaturation and the subsequent slowdown?arrow_forwardWith respect to F+ and F- bacterial matings, answer the following questions: (a) How was it established that physical contact between cells was necessary? (b) How was it established that chromosome transfer was unidirectional? (c) What is the genetic basis for a bacterium’s being F+?arrow_forward

Is Sam’s suggestion for this modification to the procedure utilized in interrupted mating experiments valid? Explain.arrow_forwardIn the Hershey–Chase experiment, the radioactive label 32P was present inside bacterial cells (i.e., in the pellet), whereas the radioactive label 35S waspresent outside bacterial cells (in the supernatant). What would the researchers have concluded had the reverse been true, that is, if the radioactive label 35S were inside the cells and the radioactive label 32P were outside the cells?arrow_forwarda) Explain how oxidation of a substrate proceeds without oxygen.
