Which base pairs with Cytosine?

Explanation:
In DNA, bases pair specifically through hydrogen bonds to keep the two strands complementary and stable. Cytosine forms three hydrogen bonds with Guanine, making this pair the strongest and helping maintain the uniform width of the helix. Adenine pairs with Thymine (two hydrogen bonds), and Cytosine pairing with itself doesn’t occur in standard DNA. So, the base that pairs with Cytosine is Guanine.
