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. However, it is inherently uns… WebMar 11, 2024 · A G:C base pair has three hydrogen bonds, because the exocyclic NH, at C2 on guanine lies opposite to, and can hydrogen bond with, a carbonyl at C2 on cytosine. Likewise, a hydrogen bond can form between N't of guanine and N3 of cytosine and between the carbonyl at C6 of guanine and the exocyclic NR, at C4 of cytosine.

WebApr 9, 2024 · The covalent bond that joins the nucleotides is called a phosphodiester bond. Each DNA strand has what is called a 5' end and a 3' end. This means that one end of each DNA strand, called the 5' end , will always have a phosphate group attached to the 5' carbon of its terminal deoxyribonucleotide (Figure \(\PageIndex{5}\)).
