Which DNA repair process identifies daughter strands by methylation?

Question

Quizplus · Accepted Answer

The process that identifies daughter strands by methylation is mismatch repair, which recognizes and repairs errors made during DNA replication. Specifically, this process detects and corrects mismatches in nucleotide base pairing that may arise due to errors during replication. In E. coli, for example, the daughter strand is distinguished from the parent strand by the presence of newly synthesized DNA lacking cytosine methylation. This signals to the repair system that the new strand is the one that needs correction. Mismatch repair is critical for maintaining genomic integrity and defects in this pathway can lead to cancer and other genetic disorders.
