In humans, what repair mechanism is used to correct thymine dimers?

Question

Quizplus · Accepted Answer

Thymine dimers, which are caused by UV radiation, are repaired by the nucleotide-excision repair mechanism in humans. This mechanism involves recognizing and removing the damaged section of DNA and replacing it with a new, correctly paired nucleotide sequence. Base-excision repair is used to correct other types of DNA damage, such as the spontaneous loss of a base from the DNA molecule. Mismatch repair corrects errors that arise during DNA replication. Photolyase is an enzyme found in some organisms that uses light energy to break apart thymine dimers, but it is not present in humans.
