Proofreading by DNA polymerase occurs during DNA replication and can immediately correct errors. Glycosylase enzyme activities and excision repair are part of the base excision repair pathway, which is effective for small, non-helix-distorting base lesions. SOS repair is a last-resort mechanism that is error-prone and used when damage is extensive.
