the rate of incorporation of nicotinamide- [ adenosine-u-14c ] adenine dinucleotide [ ( ado-u-14c ] nad ) into histones and the poly ( adpr ) polymerase activity of chromatin suggest that the nad-dependent adp-ribosylation of histones depends on the rate of nad hydrolysis by glycohydrolase in chicken liver nuclei .
