Which base pairs with Guanine in DNA?

In DNA, Guanine pairs with Cytosine through three hydrogen bonds. This specific base pairing is a key feature of the DNA structure, contributing to the stability and integrity of the double helix. The complementarity between Guanine and Cytosine is essential during DNA replication and transcription, where accurate pairing helps ensure the proper transmission of genetic information.

Other bases like Adenine and Thymine have their own pairing (Adenine pairs with Thymine), while Uracil does not appear in DNA; instead, it is found in RNA, where it pairs with Adenine. Understanding these relationships between the bases gives insight into the fundamental workings of genetic encoding and inheritance.
