Which pyrimidine base bonds with guanine?

Explanation:
Guanine is a purine, and in both DNA and RNA purines pair with pyrimidines. The pyrimidine that binds to guanine is cytosine, forming a bond through three hydrogen bonds, which makes the G–C pair particularly stable. The other pyrimidines, thymine and uracil, pair with adenine (two hydrogen bonds), and adenine is a purine that pairs with thymine or uracil. So cytosine is the base that bonds with guanine.
