3 0

Answer:

C

Explanation:

The damage to DNA usually occurs where there  are two consecutive thymine nucleotides on  a DNA strand. The energy from the UV light causes the two dimers to form a cyclobutane pyrimidine structure.  Proofreading and repair mechanism of DNA find it difficult to repair this kind of damage on DNA. During replication, therefore, DNA polymerase is unable to replicate this region hence leading to a mutation on the replicated strand at this local point.
