A compact and highly condensed form of chromatin. A condensed form of chromatin, occurring in the nucleus during interphase, that stains strongly with basophilic dyes. The DNA of heterochromatin is typically replicated at a later stage in the cell-division cycle than euchromatin. A region of heterochromatin located near the centromere of a chromosome. A ubiquitin-conjugating enzyme complex that contains two RING finger proteins, which have ubiquitin ligase activity, in addition to a protein with ubiquitin-conjugating enzyme activity; catalyzes the ubiquitination of histone H2B at lysine 119 (or the equivalent residue). In Schizosaccharomyces the subunits are Rhp1, Brl2/Rfp1 and Brl1/Rfp2. A region of heterochromatin located at the rDNA repeats in a chromosome. Heterochromatic regions of the chromosome found at silenced mating-type loci. Any constituent part of a chromosome, a structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information. Heterochromatic regions of the chromosome found at the telomeres. The ordered and organized complex of DNA and protein that forms the chromosome.
