Which of the following correctly describes the pairing in RNA?

In RNA, the pairing involves specific nucleotides that interact through hydrogen bonds, facilitating the formation of the RNA structure. The correct pairing in RNA includes cytosine pairing with guanine, which is a fundamental aspect of both RNA and DNA nucleic acid structure.

Moreover, the unique feature of RNA is that where DNA contains thymine, RNA has uracil, which pairs with adenine. This distinction is critical in understanding nucleic acid function and replication. Therefore, the statement that cytosine pairs with guanine accurately represents the nucleotide pairing rules in RNA. Understanding these pairing rules is essential for grasping the concepts of transcription and translation in protein synthesis.
