WebJul 19, 2024 · The base-pairing rules are based on the hydrogen-bonding capacity of nucleotides with their bases in the keto tautomer. A nucleotide whose base is in the enol tautomer can pair with the "wrong" base in another nucleotide. For example, a T in the rare enol isomer will pair with a keto G (Figure 7.1. 2 ), and an enol G will pair with a keto T.
