A)Both BRCA1 and BRCA2 are tumor suppressor genes that help prevent the overstimulation of cell growth. If one or both are mutated, the cell's ability to suppress tumor growth is impaired. BRCA1 and BRCA2 do not stimulate cells to undergo rapid cell division or impair translation of RNA to protein. Only germ cells undergo meiosis, not cancer cells.
