During transcription, which nitrogen base is complementary to adenine?

Explanation:
In transcription, the RNA strand that is produced is complementary to the DNA template, and RNA uses uracil instead of thymine. The base-piring rule between RNA and DNA is A pairing with U, while C pairs with G. Since thymine is a DNA base and not present in RNA, it cannot be the base pairing partner for adenine in transcription. Guanine and cytosine pair with each other, not with adenine. So the base complementary to adenine during transcription is uracil.
