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.

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.
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.
Adenine always pairs with Thymine (in DNA) or Uracil (in RNA), and Cytosine always associates with Guanine, forming the basis of this genetic code. Sequencing the viral genome involves identifying the precise sequence of nucleotides.
17 Μαρ 2022 · There are four types of nitrogenous bases in DNA. Adenine (A) and guanine (G) are double-ringed purines, and cytosine (C) and thymine (T) are smaller, single-ringed pyrimidines. The nucleotide is named according to the nitrogenous base it contains.
