a hyperthermic shift in the hyperchromicity curve of thermally denatured swine aortic-smooth-muscle-cell chromatin solubilized by digestion of nuclei with micrococcal nuclease was observed after the chromatin was incubated under conditions to allow poly- ( adp-ribose ) synthesis by the endogenous poly ( adp-ribose ) polymerase .
