WebApr 2, 2002 · Abstract. We demonstrate that the nuclear topological arrangement of chromosome territories (CTs) has been conserved during primate evolution over a period of about 30 million years. Recent evidence shows that the positioning of chromatin in human lymphocyte nuclei is correlated with gene density. For example, human chromosome 19 … WebSep 3, 2004 · The XY body is a specialized chromatin territory that forms during meiotic prophase of spermatogenesis and comprises the transcriptionally repressed sex chromosomes. Remodeling of the XY chromatin is brought about by recruitment of specific proteins to the X and Y chromosomes during meiosis, and also by post-translational …
