  • Chromatin-associated complexes have been purified from membrane-free nuclei of normal human sperm heads. They band at a sucrose buoyant density of 1.15-1.19 g/ml and contain macromolecular components which catalyze the endogenous synthesis of DNA in a reaction partially sensitive to ribonuclease pretreatment. The sedimentation rate and buoyant density of the purified reaction product, still attached to its endogenous template, demonstrate that the [3H]DNA is associated with a high molecular weight RNA, which may be serving as both template and primer. © 1977.
