The modification of histone H3 by addition of two methyl groups to lysine at position 9 of the histone.

The modification of histone H3 by addition of three methyl groups to lysine at position 9 of the histone.

Any process that stops, prevents, or reduces the frequency, rate or extent of a circadian rhythm behavior.

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 transcription mediated by RNA polymerase II.

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

The formation or destruction of chromatin structures.

The formation or destruction of chromatin structures.

The formation or destruction of chromatin structures.

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.

A cell cycle process by which the cell nucleus divides as part of a meiotic cell cycle in the male germline.

The modification of a histone by addition of one or more methyl groups to a lysine residue.

The modification of histone H3 by addition of two methyl groups to lysine at position 9 of the histone.

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

The modification of histone H3 by addition of one or more methyl groups to lysine at position 9 of the histone.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level.

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

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

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

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.

That part of the nuclear content other than the chromosomes or the nucleolus.

A condensed form of chromatin, occurring in the nucleus during interphase, that stains strongly with basophilic dyes. The DNA of heterochromatin is typically replicated at a later stage in the cell-division cycle than euchromatin.
