UV Light is a Mutagen That Can Cause

Question

UV light is a mutagen that can cause
A) depurination.
B) deamination.
C) alkylation.
D) thymine dimers.
E) oxidation.

Accepted Answer

UV light is known to cause thymine dimers, which are covalent bonds between adjacent thymine bases in DNA. Thymine dimers can lead to errors during DNA replication and transcription, potentially causing mutations. Depurination, deamination, alkylation, and oxidation are all DNA damage types caused by different types of mutagens, but they are not typically associated with UV light exposure.
