title: Heterochromatin: new possibilities for the inheritance of structure.
abstract: Significant portions of the eukaryotic genome are heterochromatic, made up largely of repetitious sequences and possessing a distinctive chromatin structure associated with gene silencing. New insights into the form of packaging, the associated histone modifications, and the associated nonhistone chromosomal proteins of heterochromatin have suggested a mechanism for providing an epigenetic mark that allows this distinctive chromatin structure to be maintained following replication and to spread within a given domain.
