title: Ultrastructural features of chromatin nu bodies.
abstract: Spread chromatin fibers and isolated chromatin fragments prepared from chicken erythrocyte nuclei were stained with dilute aqueous uranyl acetate. High-resolution electron micrographs reveal two new morphological features exhibited by many of the chromatin nu bodies: (a) lateral association of the nu body with the connecting strand, and (b) a centrally stained spot approximately 15 A wide, possibly corresponding to a hole or crevice within the nu body.
