  • UV radiations induce mutation by
Multiple choice

UV radiations induce mutation by

  1. inversion of base pairs

  2. formation of pyrimidine hydrates

  3. formation of thymine dimers

  4. deletion of a base pair

C Correct answer
Explanation

UV radiations induce mutation by formation of thymine dimer. Dimers ultimately perturb the DNA double helix and interfere with accurate DNA replication.
