Homework Answers
During xeroderma pigmentosum, at least seven genes are defective. Interestingly, these seven genes are involved in the mechanism of repair called nucleotide excision repair (NER). The mechanism is highly involved in the repair and removal of DNA damage induced by radiation. So, the correct answer is nucleotide excision repair
