Which base is the complement to cytosine?

Explanation:
Cytosine pairs with guanine through three hydrogen bonds, a pairing that helps stabilize the DNA double helix. Because of this hydrogen-bonding compatibility, guanine is the complement to cytosine. In RNA, the same C–G pairing occurs, while thymine is replaced by uracil; adenine pairs with thymine or uracil, not cytosine.
