Which statement is true about brca1 and brca2 genes? these genes were discovered in 1953. cancerous tumors often form on these genes. people can be tested for mutations on these genes. mutations of these genes lead to diabetes.

The correct answer is People can be tested for mutations on these genes.

BRCA1 and BRCA2 are the tumor suppressor genes. Tumor suppressor genes are those genes which regulate the cell cycle and prevent the formation of a tumor. BRCA1 and BRCA2 are associated with breast cancer as mutation in these genes causes breast cancer.

BRCA1 is present on chromosome 17 and BRCA2 is present on chromosome 13. Mutations on these genes are tranferred in the next progeny in an autosomal dominant pattern.

Thus, people can be tested for mutations on these genes.
