Abstract
In confirmation of earlier findings, surface-spread early diminution stages of Cyclops furcifer and C. divulsus yield numerous chromatin rings formed by the 25-to 30-nm type of fiber. Their contour lengths have a range of 0.6 →16 μm in C. divulsus and 0.4–40 μm in C. furcifer. Employing the Miller spreading technique nucleosomal chromatin rings were detected in the critical stages of diminution in a size range of 0.6–100 μm, though in lower frequencies. Instead, linear fragments of nucleosomal chromatin were found in numbers equal to or surpassing that of the rings.
