What strategies are used to ensure efficient mismatch repair? Select one or more: a. When the mismatch repair machinery encounters a mismatch, it scans the nearby DNA for a GATC site and repairs the unmethylated strand. When the mismatch repair machinery encounters a mismatch, it scans the nearby DNA for a GATC site and repairs the methylated strand. Mismatch repair occurs late in the cell cycle only after replication of the entire genome is complete. Mismatch repair occurs immediately after a region of the genome is replicated. The mismatch repair system can repair mismatches to both the 5' and 3' side of a nearby DAM methylase site because the system employs both 5' and 3' exonucleases.
