Which pyrimidine base bonds with adenine in DNA?

Explanation:
In DNA, base pairing is highly specific: adenine pairs with thymine through two hydrogen bonds. Thymine is a pyrimidine, and this A–T pairing is a defining feature of the DNA double helix. Cytosine pairs with guanine (a pyrimidine–purine pair with three hydrogen bonds), while uracil is used in RNA in place of thymine and pairs with adenine there. So, thymine is the base that bonds with adenine in DNA.
