[Irradiation of DNA with ultraviolet light: potential changes and mutations].

Molekuliarnaia biologiia - 1 Jan 2000

Grebneva E A

Abstract excerpt

It is proposed a mechanism of formation of potential changes at UV irradiation of DNA. It consists in the changes of tautomers of nucleotide bases provoked by a simultaneously hydrogen atoms transitions of first and second H-bonds in G-C pair. The reason of such transitions are strong atomic vibrations induced by electronic excitation energy into heat transition and also protons excitation. The probability of...
