Answer:
<h2>A</h2>
Explanation:
1. As given, the of a strand DNA contain sequence;
A-T-G-C-C-A-T-C-G-G-T-A,
2. After exposure to UV light, the strand contain the bases;
A-T-G-G*-C-C-A-T-C-G-G-T-A,
3. By comparing both the strands, we find that, the strand of DNA after exposure to UV contain extra G nucleotide between G and C, which is resulted by an insertion.
So we can say that, a new base has been inserted.
