Abstract The ultrastructure of subunits of compact and diffuse chromatin of isolated Wistar rat hepatocyte nuclei was studied. The complex structure of the chromatin subunits, which consist of a central nucleosome surrounded by a capsule, was confirmed. The capsule was shown to exist in either a compact or a diffuse state, and this determines the compact or diffuse state of the chromatin. It is suggested that the capsule of the nucleosome in its diffuse form is the site of transcription.
