[Analyses of histones and of nucleosomal DNA of normal and vitamin B 12 starved Euglena].
An extraction and electrophoresis of histones from normal and starved Euglena cell nuclei allows us to show the presence of five types of histones in the two cases but a lower degree of acetylation appears in H4 histone from starved cells. It was shown that DNA repeat length from the two kinds of chromatin is comparable (225 b.p.).
