Recent studies have shown that xeroderma pigmentosum (an error in the nucleotide excision repair process) can result from mutations in one of seven genes. What can you infer from this finding?
A) There are seven genes that produce the same protein.
B) These seven genes are the most easily damaged by ultraviolet light.
C) There are several proteins involved in the nucleotide excision repair process.
D) These mutations have resulted from translocation of gene segments.

Question

Quizplus · Accepted Answer

The finding that xeroderma pigmentosum can result from mutations in one of seven genes indicates that there are several proteins involved in the nucleotide excision repair process, and mutations in any of these genes can result in the disease. This suggests a high level of complexity in the nucleotide excision repair pathway.
