The BRCA2 Protein Functions in Double-Strand Break Repair

question 8

Multiple Choice

The BRCA2 protein functions in double-strand break repair.If a woman is heterozygous for a loss-of-function allele of BRCA2, she

• A)will develop cancer because two functional copies of BRCA2 are needed in every cell.
• B)will not get cancer because BRCA1 can compensate for the loss of BRCA2.
• C)will develop cancer after several mutations occur, even if the mutations occur in different clonal populations of cells.
• D)may develop cancer because mutation of the wild-type BRCA2 allele could destroy an important DNA repair mechanism.
