chromatin remodeling

chromatin remodeling
alterations in chromatin structure that affect the behavior of the chromosomes, often specifically changes in nucleosome structure causing regions adjacent to actively transcribed genes to become hypersensitive to cleavage by nucleases, as by disruption of DNA–histone contacts, releasing the histones, or by sliding of nucleosomes along the DNA.
