In RNA, Adenine pairs with which base?

Explanation:
In RNA, adenine pairs with uracil, not with thymine. RNA uses uracil in place of thymine, so A-U pairing is the standard pairing, connected by two hydrogen bonds, which helps stabilize the RNA structure. Guanine pairs with cytosine instead, and thymine isn’t present in RNA, so it cannot pair with adenine. This makes uracil the correct partner for adenine in RNA.
