[Transcription-active portions of the chromatin].
A review of data on transcriptionally active chromatin obtained during the last 5--7 years. The role of hypersensitive regions, of non-histone proteins, of DNA undermethylation and the participation of Hl histone in the organization of active chromatin are considered. The role of some of these processes in the mechanisms determining cell differentiation during ontogenesis is discussed.
