In a tautomeric shift
Valence tautomerism is a type of tautomerism in which single and/or double bonds are rapidly formed and ruptured, without migration of atoms or groups. It is distinct from prototropic tautomerism, and involves processes with rapid reorganisation of bonding electrons. A pair of valence tautomers with formula … See more Tautomers are structural isomers (constitutional isomers) of chemical compounds that readily interconvert. The chemical reaction interconverting the two is called tautomerization. This conversion commonly results … See more Prototropy is the most common form of tautomerism and refers to the relocation of a hydrogen atom. Prototropic tautomerism may be considered a subset of See more The existence of multiple possible tautomers for individual chemical substances can lead to confusion.

It is typically associated with polar molecules and ions containing functional groups that are at least weakly acidic. Most common tautomers exist in pairs, which means that the hydrogen is located at one of … See more In inorganic extended solids, valence tautomerism can manifest itself in the change of oxidation states its spatial distribution upon the change of macroscopic … See more • Fluxional molecule See more WebNational Center for Biotechnology Information

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. WebA tautomeric shift in one strand has produced a transition mutation in the complementary strand. If the mutation occurs in the germline, it will be transmitted to future generations. IMPORTANT: Note that a tautomeric …
WebScientists believed that if and when a nucleotide base shifted into its rarer tautomeric form (the "imino" or "enol" form), a likely result would be base-pair mismatching. But evidence … WebIf 5-BU is incorporated into DNA in place of thymine, the tautomeric shift will occur, and the 5-BU will base pair with guanine. 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. Fig. 2.23.
