A heavy metal environmental toxicant, cadmium, can inactivate an important cellular repair system, NIEHS researchers showed. Cadmium was found to cause mutations in DNA by inhibiting DNA mismatch repair. This mismatch repair system is important for keeping mutations from occurring during DNA synthesis.
