The correct answer to this question is A, A DNA sequence made with multiple cytosines. Cytosine is a base found in both DNA and RNA. There are four bases and cytosine is one of them. The other three bases are thymine, guanine, and adenine. Cytosine has a number of purposes.

One of the purposes is to store genetic information, as well as transport the information. In both DNA and RNA, cytosine pairs with guanine. When these two are paired, they are unstable and at any moment can change into uracil. If this change does occur, it can lead to mutation.
