Repression of transcription of ribosomal DNA by altering the structure of chromatin.

Any process that results in the specification, formation or maintenance of the physical structure of eukaryotic chromatin.

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 damage to its DNA from environmental insults or errors during metabolism.

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.

Any process that modulates the frequency, rate or extent of DNA repair.

Any process in which DNA and associated proteins are formed into a compact, orderly structure.

Repression of transcription by altering the structure of chromatin, e.g. by conversion of large regions of DNA into an inaccessible state often called heterochromatin.

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 damage to its DNA from environmental insults or errors during metabolism.

The control of viability and duration in the adult phase of the life-cycle.

Any process that modulates the frequency, rate or extent of bone mineralization.

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

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.

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.

Any process that activates or increases the frequency, rate or extent of histone H3-K9 trimethylation.

Any process that modulates the frequency, rate or extent of cellular senescence.

A compact and highly condensed form of chromatin.

A compact and highly condensed form of chromatin.

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.

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.

Any protein complex that mediates changes in chromatin structure that result in transcriptional silencing.

A highly compacted molecule of DNA and associated proteins resulting in a cytologically distinct nuclear 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.
