Chromatin rings as products of chromatin diminution in Cyclops
- 48 Downloads
Nuclei from the interphase preceding the 6th cleavage (=first diminution) division of Cyclops furcifer were subjected to a micro-spreading technique (Counce and Meyer, 1973) and examined by electron microscopy. In some preparations numerous chromatin rings formed by 250–300 Å fibers were discovered in sizes ranging from 0.25 μm to more than 6 μm. These structures are assumed to represent the primary products of chromatin diminution.
