Tautomerism in dna bases
Webtautomerism, the existence of two or more chemical compounds that are capable of facile interconversion, in many cases merely exchanging a hydrogen atom between two other atoms, to either of which it forms a covalent bond. WebTautomers are the alternate forms of bases and are produced by rearrangements of electrons and protons in the molecules (Fig. 6.46). Tautomerism is caused by certain …
