it was shown that the nad-pyrophosphorylase activity in chicken liver nuclei treated with n-methyl-n-nitrosourea does not differ from the control one , while in dnaase i-treated nuclei the maximum of the nad-pyrophosphorylase activity was achieved , as well as the maximum of [ 14 ] nad incorporation into the histones within the range of dna damage of 25-35 % , being equal to 37 x 10 ( -8 ) mm nad/min/mg protein as compared to 26.0 x 10 ( -8 ) mm/min/mg protein in the control .
