After the replication, an A-T to G-C transition occurs. Furthermore, the presence of 5-BU within DNA increases the sensitivity of the molecule to UV light.

Tautomer - Wikipedia

WebTautomeric shift is an intramolecular proton shift that changes the bonding structure of the molecule. Tautomeric shift is an intramolecular electron shift that changes the bonding structure of the molecule. How may it lead to a mutation? It allows hydrogen bonding of normally noncomplementary bases. WebTautomerism is an especially important equilibrium in 1,3-dicarbonyl compounds. There are two equilibria taking place, namely keto(1)-enol and enol(2a)-enol(2b). The enol-enol equilibrium is very fast Figure 1– Molecular schematic for the keto-enol equilibrium in 2,4 pentanedione, commonly referred to as acetylacetone (acac). WebA tautomer is a particularly kind of constitutional isomer in which the molecules readily interconvert between the two forms. A tautomer is a type of constitutional isomer, but constitutional isomers aren't necessarily tautomers. Comment ( 28 votes) Upvote Downvote Flag more Show more...
