- Explain the term inducer.arrow_forwardUsually, bacteria only make tryptophan when tryptophan is absent or available in low concentration. However, a particular bacterial mutation makes tryptophan all the time whether or not tryptophan is present. What could explain this phenotype? A) the terminator hairpin is unable to form B) the antiterminator hairpin is unable to form C) trpE is mutated D) trpD is mutated E) trpA is mutatedarrow_forwardI read that vinyl chloride exposure is associated with an increased risk of a rare form of liver cancer (hepatic angiosarcoma), as well as brain and lung cancers, lymphoma, and leukemia. But my question is what gene(s) are being mutated by this type of taxic gas?arrow_forward
- What is a possible outcome of the addition of a transcription factor such as Myod to the nucleus of a cell? Assume that there are no other factors to either activate or prevent the response of the cell.

- Why are proto-oncogenes present in non-cancerous cells? A one sentence answer is fine.arrow_forwardWhy is p53 considered a tumor suppressor protein? Question 12 options: a) Because p53 normally detects breaks in DNA. b) Because p53 normally causes progression from G1 to S phase to halt until damaged DNA is fully repaired. c) Because p53 normally repairs breaks in DNA. d) Because p53 normally stimulates transcription of Repair Polymerase. e) Because p53 normally reduces the mutation rate of DNA polymerase.arrow_forwardIn Hershey-Chase experiment, bacteriophages protein coats were tagged with radioactive isotope S-32. These phages were used to infect E. coli cells and the cells were further centrifuged to form pellets. Why was the radioactivity level of S-32 found greater outside the cells compared to the E. coli cell pellets? Explain briefly. If the experiment is repeated in the same manner but this time the phage protein coats are labelled with isotope X and the phage DNA with isotope Y, which isotope’s radioactivity will be found in greater amounts in the E. coli cell pellets after centrifugation? Explain briefly.arrow_forward
