Nitrogen base that pairs with adenine in RNA.
The nitrogen base that pairs with adenine in RNA is uracil (U)
The nitrogen base that pairs with adenine in RNA is uracil (U). In RNA, uracil takes the place of thymine (T) which pairs with adenine in DNA. Both uracil and thymine are pyrimidine bases, consisting of a single ring structure. Adenine, on the other hand, is a purine base, which consists of a double-ring structure. During transcription, when RNA is synthesized from a DNA template, adenine in the DNA pairs with uracil in the RNA. This specific pairing between adenine and uracil is facilitated by complementary hydrogen bonding. Adenine and uracil form two hydrogen bonds, which provide stability to the RNA molecule. This base pairing is crucial for the accurate replication and translation of genetic information in the cell.
