A compact and highly condensed form of chromatin. A region of heterochromatin located near the centromere of a chromosome. A diffusely banded region of heterochromatin located between euchromatin and alpha-heterochromatin in the polytene chromosome chromocenter; normally replicated during polytenization. A small, compact region of heterochromatin located in the middle of the polytene chromosome chromocenter, which undergoes little or no replication during polytenization. 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. A region of heterochromatin located near the centromere of a chromosome in the nucleus. The ordered and organized complex of DNA and protein that forms the chromosome. The region of a chromosome that includes the centromeric DNA and associated proteins. In monocentric chromosomes, this region corresponds to a single area of the chromosome, whereas in holocentric chromosomes, it is evenly distributed along the chromosome.
