The Dam Methylase Has a Role in Which of the Following

Question

The dam methylase has a role in which of the following DNA repair systems?
A) Base-excision repair
B) Nucleotide excision repair
C) Non-homologous end-joining
D) Mismatch repair
E) Homologous recombination

Accepted Answer

The dam methylase plays a role in mismatch repair by identifying and repairing errors in the newly synthesized strand of DNA during DNA replication. The methylase specifically methylates the adenine nucleotide in the GATC sequence, which serves as a recognition site for the mismatch repair system.
