Base-pairing takes place between a purine and pyrimidine: namely, A pairs with T, and G pairs with C. In other words, adenine and thymine are complementary base pairs, and cytosine and guanine are also complementary base pairs.

Cytosine can be found as part of DNA, as part of RNA, or as a part of a nucleotide. As cytidine triphosphate (CTP), it can act as a co-factor to enzymes, and can transfer a phosphate to convert adenosine diphosphate (ADP) to adenosine triphosphate (ATP). In DNA and RNA, cytosine is paired with guanine.
cytosine, a nitrogenous base derived from pyrimidine that occurs in nucleic acids, the heredity-controlling components of all living cells, and in some coenzymes, substances that act in conjunction with enzymes in chemical reactions in the body.

15 Μαΐ 2022 · The rules of base pairing explain the phenomenon that whatever the amount of adenine (A) in the DNA of an organism, the amount of thymine (T) is the same (called Chargaff's rule). Similarly, whatever the amount of guanine (G), the amount of cytosine (C) is the same.
27 Απρ 2020 · In this article, we show, in the specific case of SARS‐CoV‐2, that the role of cytosine‐based metabolites used as cell growth coordinators is central to understanding both innate antiviral immunity and the evolution of the virus.
In DNA, cytosine pairs with guanine through three hydrogen bonds, forming a stable base pair. The sequence of these base pairs along the DNA strand encodes genetic information. During DNA replication, the complementary base pairing ensures faithful copying of the genetic material.
