Centric heterochromatin : ウィキペディア英語版 | Centric heterochromatin
Centric heterochromatin, a variety of heterochromatin, is a tightly packed form of DNA. Centric heterochromatin is a constituent in the formation of active centromeres in most higher-order organisms; the domain exists on both mitotic and interphase chromosomes. Centric heterochromatin is usually formed on alpha satellite DNA in humans; however, there have been cases where centric heterochromatin and centromeres have formed on originally euchromatin domains lacking alpha satellite DNA; this usually happens as a result of a chromosome breakage event and the formed centromere is called a ''neocentromere''.〔 Centric heterochromatin domains are flanked by pericentric heterochromatin.〔 ==See also==
