Verified
Individuals with mutations in excision repair enzymes may suffer from ____ due to unrepaired DNA damage caused by ____.
A) skin cancer; mutations inherited from their parents
B) colon cancer; the passing of DNA mutations to daughter cells
C) prostate cancer; telomerase
D) skin cancer; the sun's UV rays
E) skin cancer; complementary base pairing
Excision Repair Enzymes
A class of enzymes involved in the repair of DNA by recognizing and removing damaged or mismatched nucleotides, followed by filling in the correct sequences.
UV Rays
Short-wavelength ultraviolet radiation that is not visible to the human eye, capable of causing skin burns, eye damage, and other health issues.
Telomerase
An enzyme that adds specific DNA sequence repeats ("telomeres") to the ends of DNA strands in the telomere regions, thereby extending the life of cells.

Final Answer :
D
Explanation :
Individuals with mutations in excision repair enzymes are more susceptible to skin cancer due to the accumulation of unrepaired DNA damage. The sun's UV rays are a primary source of such damage, leading to mutations that can result in cancer if not properly repaired.
