A researcher exposes a bacterial culture to UV radiation and then subjects it to progressively higher temperatures. As the temperature increases, the bacteria have a progressively harder time surviving. Analysis of the dead bacteria reveals large amounts of misfolded, aggregated proteins compared to wild-type control bacteria exposed to the same temperature increase. Which of the following is a plausible explanation for the data?
A. The ribosomes are mutated and are non-functional.
B. The initiator tRNA (fMet) has been mutated and is non-functional.
C. Molecular chaperones have been mutated.
D. DNA polymerase is mutated and non-functional.

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sisterβs risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
