Ciliated protozoans possess two types of nuclei; a transcriptionally silent micronucleus, which serves as the germ line nucleus… Expand Some stages of macronuclear anlagen development, known from earlier investigations (see Fig. 1), were studied in detail. The… Expand BackgroundThere is considerable heterogeneity in the phyletic patterns of major chromosomal DNA-binding proteins in archaea. Alba… Expand Programmed DNA rearrangements, including DNA diminution, characterize the differentiation of somatic from germline nuclei in… Expand DNA rearrangements in Paramecium lead to the formation of macronuclear chromosomes, the sizes of which range from 50 and 800 kb… Expand The cortical pattern mutant broadened cortical domains (bcd) in Tetrahymena thermophila is unable to complete the nuclear events… Expand The objective of this study was to test the idea that the macronuclear (somatic) genetic information is randomly distributed at… Expand DNA isolated from macronuclei of the ciliate, Tetrahymena pyriformis, has been found to contain [6N]methyl adenine (MeAde); this… Expand DNA amounts in macronuclei and micronuclei of Tetrahymena pyriformis were measured by Feulgen microspectrophotometry. Assuming… Expand
