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 …

The structure of hen erythrocyte chromatin fibers was studied with the electron microscope.
Chromatin fiber fragments with a length of about 5,000 Å and an average diameter of 320 Å …

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 …

To examine the internal structure of chromatin fibers, we have developed procedures for
partial denaturation of small chromatin fragments (8-30 nucleosomes) from chicken …

This bibliographic review, the first of a series of three on chromatin structure, discusses the
current knowledge and hypotheses concerning chromatin organization in nucleosomes and …

Higher-order chromatin fibers (200--300 A in diameter) are reproducibly released from
nuclei after lysis in the absence of formalin and/or detergent. Electron microscope analysis …

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

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 …

Robert T. Simpson abstract: I have prepared chromatin particles from chicken erythrocytes
which contain a 160 base pair length of DNA, an octamer of the four smaller histones, and a …

In this study we addressed the question of whether scaffold structures produced from
purified mitotic chromosomes are an artefact of dehistonization, and whether the integrity of …
