Give four specific counter examples for why each of the following definitions for a gene are incorrect. for each definition, there may be several possible counter examples. for full credit, each counter example should be distinct. for example, if a friend of yours claimed that "a gene is all the dna sequences that determine an inherited trait", you could reply: "no, that is incorrect, because multiple genes will often determine an inherited trait."a. "a gene is a sequence of nucleotides from a start codon to a stop codon."b. "a gene is a sequence of nucleotides that codes for a functional protein."c. "a gene is a sequence of nucleotides that codes for an rna molecule (which may be translated)."d. "a gene is the entire dna sequence that affects the production of a protein."

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
