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. WebIn a solution, you won't see much of the enol form, but these can occur. It can spontaneously through equilibrium get to the actual enol form. And so you could imagine, these are …

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). ct scan kings college hospital

Tautomeric shift - Oxford Reference

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 … WebIn basic medium, a bathochromic shift (λ=513 nm, ε=14,100 Lmol −1 cm −1) can be seen for the Orange 1: the color turns then from orange to red. The phenate form is predominant … WebThe predicted spectral data suggest that the shift from the enol to the keto tautomer should be accompanied by a red shift in the absorption spectra and up field of the tautomeric … ct scan kidneys with contrast
