Which of the Following Causes Mutations by Creating Thymine Dimers

Question

Which of the following causes mutations by creating thymine dimers?
A) nucleotide analogs
B) nitrous acid
C) ultraviolet light
D) benzopyrene
E) gamma rays

Accepted Answer

Ultraviolet light can cause thymine dimers, which is a type of mutation where two adjacent thymine bases on a DNA strand become covalently linked. This can lead to errors in DNA replication and transcription.
