The structure that they are showing is the general structure of an amino acid. If you look at the left side there's NH2 (an amino group). On the right side is COOH (a carboxylic acid group) and the R is the part that varies depending on the amino acid --this way you can make up the 20 different amino acids but all with the basic structure shown in the diagram.
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.
