Which base pairs with Adenine in DNA?

Explanation:
In DNA, base pairing follows specific rules that keep the double helix uniform in width. Adenine forms two hydrogen bonds with thymine, so they pair together as the A–T pair in DNA. Uracil is used in RNA instead of thymine, so it doesn’t pair with adenine in DNA. The other canonical pairing in DNA is guanine with cytosine, not with adenine. Therefore, the base that pairs with adenine in DNA is thymine.
