[Differences in the ultrastructure of the subunits of compact and diffuse chromatin].
The ultrastructure of subunits of the compact and diffuse chromatin of isolated Wistar rat hepatocytes nuclei was studied. The complexity of the chromatin subunits composed of the centrally situated nucleosome and of its capsule was confirmed. It was found that the capsule could exist in either compact or diffuse form, thus determining whether the chromatin was compact or diffuse. The capsule of the nucleosome in its diffuse form was supposed to represent the site of transcription.
