Solution
UV radiation causes formation of pyrimidine dimers in DNA due to which two bases (thymine) get joined by covalent linkage to form a dimer. These dimers can lead to mutations as during replication, these dimers are skipped. However, certain enzymes are there which repair the damaged DNA.
So, the correct answer is 'Formation of thymine dimers'.
