A chemical compound would increase the mutation rate if it inhibited:

Question

Quizplus · Accepted Answer

All of these choices are correct because they all involve mechanisms that repair DNA. Inhibiting any of these processes would prevent the correction of errors in the DNA, leading to an increased mutation rate. Mismatch repair corrects base-pair mismatches, nucleotide excision repair removes bulky lesions, base excision repair fixes small, non-helix-distorting base lesions, and DNA ligase seals nicks in the DNA backbone.
