The statements concern genes and proteins linked to breast cancer. • The protein produced by the BRAC1 gene prevents breast cancer cells from growing. • The protein produced by the p53 gene reduces tumour growth. Which pairing of genes is most likely to cause breast cancer?
- ABRAC1: mutated; p53: mutated
- BBRAC1: mutated; p53: normal active
- CBRAC1: normal active; p53: mutated
- DBRAC1: normal active; p53: normal active
