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

Any process in which an organism modulates its heart rate at different values with a regularity of approximately 24 hours.

The specific behavior of an organism that recur with measured regularity.

Any biological process in an organism that recurs with a regularity of approximately 24 hours.

Any biological process in an organism that recurs with a regularity of approximately 24 hours.

Any biological process in an organism that recurs with a regularity of approximately 24 hours.

The timing of the emergence of the adult fly from its pupal case, which usually occurs at dawn.

The timing of the emergence of the adult fly from its pupal case, which usually occurs at dawn.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a temperature stimulus.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a temperature stimulus.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a light stimulus, electromagnetic radiation of wavelengths classified as infrared, visible or ultraviolet light.

The synchronization of a circadian rhythm to environmental time cues such as light.

Any process that modulates the frequency, rate or extent of gene expression such that an expression pattern recurs with a regularity of approximately 24 hours.

Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.

Any process that modulates the frequency, rate or extent of sleep; a readily reversible state of reduced awareness and metabolic activity that occurs periodically in many animals.

The rhythm of the locomotor activity of an organism during its 24 hour activity cycle.

The rhythm of the locomotor activity of an organism during its 24 hour activity cycle.

The rhythm of the locomotor activity of an organism during its 24 hour activity cycle.

Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.

Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.

Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that results in a change in the behavior of an organism as a result of a cocaine stimulus.

Any process that results in a change in the behavior of an organism as a result of a cocaine stimulus.

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.

Transcription factor complex which interacts with E-box regulatory elements in target genes, including Period (Per1, Per2, Per3) and Cryptochrome (Cry1, Cry2), to activate their transcription during the daytime. The CRY-PER complexes inhibit CLOCK-BMAL1-driven transcription in a negative feedback loop to generate circadian rhythms.
