摘要: Summary As it was shown previously the chromatin of heteromeric macronucleus Chilodonella steini consists two specific zones, outer one (the orthomere) made up from late replicating electron dense material, and inner zone paramere) medium density early replicating, with a concentration material called endosome in its central part. New details regarding reorganization after macronuclear division are presented here. After no is visible. It reappears within first hours separation sister macronuclei. With use situ rDNA — DNA hybridization that located (orthomere) endosome. Since has been found earlier content depends on culture conditions authors suggest quantitative changes caused preferentially by differential replication dependent food cells.
