The organization of nucleosomes in higher order chromatin structures has been studied by
electron microscopy of chick red blood cell nuclei. Chromatin appears as a thick fiber with an …

The effect of selective removal of histone proteins from chicken erythrocyte nuclei on the
process of reversible dispersal of chromatin in low ionic strength was examined in electron …

Small-angle neutron scattering studies of chromatin core particles suggest a structure
comprising a nearly spherical histone core (of~ 3.2 nm radius and with which is associated …

Electron microscopic and biochemical studies demonstrate that the fundamental structure of
chromatin depleted of lysine-rich histones is composed of a flexible chain of spherical …

Both intact and nuclease-isolated chromatin fibers have been examined at different degrees
of salt-induced compaction, using a variety of preparation techniques. The results suggest …

Adolfo Ruiz-Carrillo,** Pere Puigdomenech,* Gabi Eder, and Rudolf Lurz abstract: The
organization of the higher order structure of chromatin has been examined in chicken …

ABSTRACT A unit thread has been identified by electron microscopy as the common
structural element in the condensed chromatin of a variety of cell nuclei. From the previous …

Neutron scattering in solution and scanning transmission electron microscopy were
simultaneously done on chicken erythrocyte chromatin at various salt and magnesium …

Three classes of chicken erythrocyte chromatin particles differing in their content of lysine-
rich histones and/or spacer DNA have been studied in order to determine their ability to …

Structural transitions between extended and condensed forms of chromatin have been
studied by electron microscopy of whole chicken erythrocyte nuclei incubated in low buffer …
