Why do mutations in genes that encode DNA-repair enzymes often produce a predisposition to cancer?
DNA sequencing has provided data to indicate that cancer cells may contain tens of thousands of somatic mutations, only some of which confer a growth advantage to a cancer cell. How do scientists describe and categorize these recently discovered populations of mutations in cancer cells?
