The information given concerns genes and proteins that play a role in breast cancer. • The protein encoded by the $\text{BRAC1}$ gene slows the growth of breast cancer cells. • The protein encoded by the $\text{RAD51}$ gene is needed to repair damaged DNA. Which pair of genes is most likely to lead to breast cancer?
- A$\text{BRAC1}$ normal, $\text{RAD51}$ normal
- B$\text{BRAC1}$ mutated, $\text{RAD51}$ normal
- C$\text{BRAC1}$ normal, $\text{RAD51}$ mutated
- D$\text{BRAC1}$ mutated, $\text{RAD51}$ mutated
