Question

The genetic condition Xeroderma pigmentosum, which can lead to skin cancer, results from A. inability to correct UV induced lesions B. inability to process phenylalanine. C. inability to produce functional hemoglobin. D. inability to correct transitions E. breaks in the X chromosome

Answer 1

Answer:

Option A

Explanation:

Xeroderma pigmentosum arises as a result of the cell being unable to correct lesions induced by UV. This can be as a result of mutations in the enzymes which include XP A-E needed for correction of the lesions. Failure to correct these lesions leads to their accumulation and then damage to the cell.
