Which base pairs with Adenine?

Explanation:
Base pairing is highly specific in DNA. Adenine pairs with Thymine because they form two hydrogen bonds that fit together snugly, helping to keep the double helix uniform in width. This specific pairing means Adenine’s partner is Thymine, not Cytosine or Guanine (which pair with each other via three hydrogen bonds). A quick reminder: in RNA, Adenine pairs with Uracil instead of Thymine.
