electrophoretic analysis of nucleoprotein particles produced by micrococcal nuclease digestion of nuclei indicates that ( 1 ) the distribution of mononucleosome species changes during hu block and ( 2 ) some mononucleosome species appear to be enriched in normally minor proteins which may determine the electrophoretic mobility of the nucleoprotein particles in agarose-acrylamide gels .
