The present study was undertaken to test the reproducible formation of the extended chromatin fibres (ECF), beads and superbeads, and detect molecular order and crystallinity by optical anisotropies in those structures. Chicken erythrocyte smears and mouse liver cell imprints were treated with 2.0–3.0
Key words: extended chromatin fibres, nucleus, structural ordering, crystlaline array, concanavalin-A binding.
