Abstract
Histones were extracted from isolated macro- and micronuclear fractions and from nucleohistone fibers which were prepared from the isolated macronuclear fraction. Analysis of these histones by polyacrylamide gel electrophoresis indicated that there are electrophoretic differences between the histones of macro- and micronuclei.
