In RNA, adenine pairs with which base?

Explanation:
In RNA, base pairing follows complementary rules, with uracil taking the place of thymine. Adenine pairs with uracil because they form two hydrogen bonds, connecting a purine to a pyrimidine and giving a stable A–U pair. This pairing helps RNA strands fold into regions of double-stranded character and supports proper transcription-related interactions. The other standard pairing is guanine with cytosine, while thymine is absent in RNA.
