Guanine pairs with which base?

Explanation:
DNA base pairing is specific: Guanine forms three hydrogen bonds with Cytosine, creating a stable G–C pair that fits well with the DNA backbone’s geometry. This complementary pairing helps the double helix stay together and ensures accurate replication. In contrast, Adenine pairs with Thymine in DNA (and with Uracil in RNA), not with Guanine. Therefore, Cytosine is the correct partner for Guanine.
