SINGULAR KINETOCHORE STRUCTURE IN A PARASITIC DINOFLAGELLATE

Normally kinetochores have three-layered structures: the inner part containing DNA, the outer part RNA, and between them a transfer area. This structure can be observed as well in higher organisms as in Protozoa. But in some Dinoflagellates such as Apodinium and most of the free-living ones (Amphidinium …) this structure is quite different. Our observations allow us to conclude that only the chromosomes which bear histones may have typically trilaminar kinetochores. © 1979, VEB Gustav Fischer Verlag Jena. All rights reserved.
