What pairs with adenine in RNA?

• A. Thymine
• B. Uracil
• C. Cytosine
• D. Guanine

Answer: (B)

In RNA, adenine pairs with uracil. This pairing is essential in the formation of RNA molecules, as it allows for the correct encoding of genetic information during processes such as transcription. Unlike DNA, which contains thymine that pairs with adenine, RNA substitutes uracil for thymine. Therefore, whenever adenine is present in an RNA strand, uracil will pair with it to create stable hydrogen bonds, facilitating the proper structure and function of the RNA molecule. This is a fundamental aspect of nucleic acid biology and is crucial for various cellular processes, including protein synthesis.
