WebMutations can also be caused by exposure to specific chemicals or radiation that cause the DNA to break down. Cells do have mechanisms to repair damaged or altered DNA molecules, but they aren’t perfect. Whatever the cause, mutations occur any time a cell ends up carrying a DNA sequence slightly different than the original. Digging Data WebDNA repair, any of several mechanisms by which a cell maintains the integrity of its genetic code. DNA repair ensures the survival of a species by enabling parental DNA to be inherited as faithfully as possible by offspring. It also preserves the health of an individual.
