title: Chromatin structure in the macronucleus of the ciliate Stylonychia mytilus.
abstract: Evidence is presented that macronuclear chromatin in the hypotrichous ciliate Stylonychia mytilus occurs in discrete fragments, each representing at least single genes. The size of these fragments varies between 3 and more than 70 nucleosomes with an average length of about 18 nucleosomes. This observation is discussed with respect to macronuclear structure of hypotrichous ciliates.
