WebFeb 9, 2024 · How does guanine bind to cytosine? Guanine has two tautomeric forms, the major keto form (see figures) and rare enol form. It binds to cytosine through three … WebCytosine and guanine are important pyrimidine bases that are parts of the basic building units of DNA, namely the nucleotides. They both have three centers for hydrogen bonding to be formed between them (base pairing) when the two strands of DNA are joined.

Qualitatively, guanine (G) and cytosine (C) undergo a specific hydrogen bonding with each other, whereas adenine (A) bonds specifically with thymine (T) in DNA and with uracil (U) in RNA. Quantitatively, each GC base pair is held together by three hydrogen bonds, while AT and AU base pairs are held together by two hydrogen bonds. To emphasize this difference, the base pairings are often represented as "G≡C" versus "A=T" or "A=U".
