In RNA base pairing, which of the following base pairs correctly corresponds?

In RNA, the base pairing rules are distinct from those of DNA due to the differences in nitrogenous bases. In RNA, adenine (A) pairs with uracil (U) instead of thymine (T), which is found in DNA. Additionally, cytosine (C) pairs with guanine (G) as it does in DNA.

The correct pairing is A=U and C=G. This means that adenine bonds with uracil in RNA, effectively substituting thymine, and cytosine pairs with guanine as per the complementary base pairing that maintains the structure of the RNA molecule. This pairing is crucial for processes such as transcription and translation, which are fundamental for protein synthesis in cells.

The other options propose incorrect pairs or include bases not typically found in RNA, leading to underlying misunderstandings regarding base pairing in nucleic acids. For example, thymine is not present in RNA, impacting the proposed relationships in those incorrect choices. Understanding these specific pairings is essential for grasping the mechanisms of molecular biology.
