Question

Quizplus · Accepted Answer

The excision repair system is specifically responsible for repairing DNA mutations caused by exposure to UV light. This system works by identifying and removing the damaged section of DNA and then filling in the gap with newly synthesized DNA. Mismatch repair and proofreading are involved in correcting errors that arise during DNA replication, while polymerase and ligase are involved in the process of DNA replication and repair, but not specifically in repairing UV-induced mutations.
