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.

Any process that stops, prevents, or reduces the frequency, rate or extent of heterochromatin formation.

Any process that stops, prevents, or reduces the frequency, rate or extent of heterochromatin formation.

The process involved in the specification of cell identity. Once specification has taken place, a cell will be committed to differentiate down a specific pathway if left in its normal environment.

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.

Any process that modulates the frequency, rate or extent of transcription mediated by RNA polymerase II.

Any process that restricts, stops or prevents a cell from adopting a specific cell fate.

The process in which a cell becomes capable of differentiating autonomously into a neuroblast in an environment that is neutral with respect to the developmental pathway. Upon specification, the cell fate can be reversed.

Any process that affects the structure and integrity of a protein, altering the likelihood of its degradation or aggregation.

Any process that affects the structure and integrity of a protein, altering the likelihood of its degradation or aggregation.

Any process that reduces the extent of heterochromatin formation; reduces the size of a chromosomal region converted to heterochromatin.

Any process that modulates the frequency, rate or extent of development of the vulva. Vulval development is the process whose specific outcome is the progression of the egg-laying organ of female and hermaphrodite nematodes over time, from its formation to the mature structure. In nematodes, the vulva is formed from ventral epidermal cells during larval stages to give rise to a fully formed vulva in the adult.

The replacement, within chromatin, of resident histones or histone subunits with alternative, sometimes variant, histones or subunits.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

The cellular homeostatic process that preserves a muscle cell in a stable functional or structural state.

The cellular homeostatic process that preserves a muscle cell in a stable functional or structural state.

Any process in which a protein is transported to, or maintained at, a part of a chromosome that is organized into chromatin.

Locomotion in a multicellular organism, i.e. self-propelled movement of a multicellular organism from one location to another.

Locomotion in a multicellular organism, i.e. self-propelled movement of a multicellular organism from one location to another.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

The part of a cell encompassing the cell cortex, the plasma membrane, and any external encapsulating structures.

The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome in the nucleus.

A multisubunit protein complex that is involved in chromatin remodeling. It is required for the incorporation of the histone variant H2AZ into chromatin. In S. cerevisiae, the complex contains Swr1p, a Swi2/Snf2-related ATPase, and 12 additional subunits.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information.

The intracellular plane, located halfway between the poles of the spindle, where chromosomes align during metaphase of mitotic or meiotic nuclear division.
