title: Fine structure of human sperm chromatin.
abstract: The fine structure of human sperm chromatin is revealed by electron microscopy. Human sperm chromatin is characterized by fibers composed of discrete spherical organizational units not unlike somatic nucleosomes. During the decondensation process fibers composed of joined spherical units of both 400-A and 150-A diameters were observed.
