Cytosine to thymine

WebMay 31, 2024 · In DNA, adenine always pairs with thyine and cytosine always pairs with guanine. These pairings occur because of geometry of the base,s allow hydrogen bonds to form only between the “right” pairs. Adenine and thymine will form two hydrogen bonds, whereas cytosine and guanine will form three hydrogen bonds. WebThere 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 …
