Question

Quizplus · Accepted Answer

Base excision repair removes damaged bases, such as those damaged by reactive oxygen species (ROS). Mismatched bases are repaired by the mismatch repair pathway, and uracil is specifically recognized and removed by uracil-DNA glycosylase. While some methylation damage may be recognized and repaired by base excision repair, other types of methylation damage require different repair pathways.
