Which base pairs with cytosine in nucleic acids?

Explanation:
Base pairing in nucleic acids depends on complementary hydrogen bonding and fitting shapes. Cytosine pairs with guanine because their functional groups align to form three hydrogen bonds, giving a stable C–G pair in both DNA and RNA. The other bases pair with different partners: adenine pairs with thymine in DNA (or with uracil in RNA), not with cytosine; thymine pairs with adenine; uracil pairs with adenine. So the partner for cytosine is guanine.
