Structural changes to eukaryotic chromatin occurring as a result of cation stress, an increase or decrease in the concentration of positively charged ions in the environment. The initial formation of a transcriptionally silent chromatin structure such as heterochromatin. The assembly of chromatin into heterochromatin, a compact and highly condensed form that is often, but not always, transcriptionally silent. Dynamic structural changes to eukaryotic chromatin that require energy from the hydrolysis of ATP, ranging from local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation, mediated by ATP-dependent chromatin-remodelling factors. The movement of nucleosomes along a DNA fragment. Any process that results in the specification, formation or maintenance of the physical structure of eukaryotic chromatin. Dynamic structural changes in centromeric DNA. Dynamic structural changes to eukaryotic chromatin occurring throughout the cell division cycle. These changes range from the local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation. Maintenance of transcription by remodelling of chromatin into an 'open configuration'. Once established, this regulation is mitotically stable and is maintained over many cell divisions. It is also heritable. The alteration of DNA or protein in chromatin, which may result in changing the chromatin structure.
