WebCan mutations be repaired? How? Yes, mutations can be reperired thash excision repas mechanism and throush photolyases. 4. Which makes a larger contribution to DNA mutations, natural background radiation or consumer products? 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
