Which repair mechanism identifies daughter strands by methylation?

Question

Quizplus · Accepted Answer

Mismatch repair is the mechanism that identifies and corrects errors generated during DNA replication. It involves the recognition of mismatches by specific enzymes that detect changes in the base pairing, followed by excision of the mismatched nucleotide and synthesis of a new strand using the template as a guide. In bacteria, the parental DNA strand is methylated, while the newly synthesized strand is not. This allows the mismatch repair system to distinguish between the two strands because the unmethylated strand is the one that contains the error. In eukaryotes, a similar process occurs, but the identification of the new strand is more complex and involves multiple factors.
