Abstract

Autodegradation of the chromatin contents of human sperm cells occurs in the presence of dithiothreotol at pH 8.0. The products of this degradation are chromosomal fragments containing DNA molecules ∼25 K b.p. in length and showing spheroidal subunit structure. From the length of these fragments the direction of one axis of a crystalline organization of human sperm chromatin is suggested.
