| Popis: | It is shown that luminescence spectra of DNA, total histone (TH) and nucleohistone (NH) are the same under UV and VUV excitation. The luminescence quantum efficiency falls with a decrease of excitation wave length to 120 nm. This effect is connected with absorption screening of aliphatic amino acids, peptide, and ribosophosphate groups (lambda220 nm), with photoionization of DNA (160-120 nm) and photodestruction of tyrosine in TH (lambda200 nm). |
