Which base replaces Thymine in RNA and pairs with Adenine?

Explanation:
RNA uses uracil instead of thymine, and uracil pairs with adenine. This pairing mirrors the adenine–thymine rule in DNA, ensuring the genetic code is correctly read during transcription. Cytosine pairs with guanine as well. So, the base that replaces thymine in RNA and pairs with adenine is uracil.
