How are the BRCA proteins and their genes implicated in breast cancer?

#Section 3: Genetics, Cellular and Molecular Biology

  1. The BRCA proteins damage DNA by generating double-stranded breaks which can lead to cancer.

  2. Cells become more susceptible to damage if the genes for these proteins are damaged.

  3. BRCA proteins inhibit excision repair mechanisms.

  4. BRCA proteins initiate recombination between non-homologous DNA sequences.
