A science researcher has developed a computer model of the process of DNA replication in a eukaryotic cell. The model includes the following
sequence of bases in one strand of the DNA molecule.

The researcher wants to revise the model to show the transcription of DNA to form mRNA
Which of these revisions to the model would be most useful for the researcher to include?
A
Replace thymine (T) with uracil (U) in the DNA molecule.
B. Keep the two strands of the DNA molecule joined together.
C. Identify promoter and "stop" regions on the DNA molecule.
D. Divide the DNA molecule into pieces that are 40 to 50 bases long

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 sister’s 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
