Any process that modulates the consistent predetermined time point at which an integrated living unit or organism progresses from an initial condition to a later condition and the rate at which this time point is reached.

Any process that modulates the frequency, rate or extent of programmed cell death, cell death resulting from activation of endogenous cellular processes.

The process aimed at the progression of a neuroblast over time, from initial commitment of the cell to a specific state, to the mature neuroblast. It does not include processes where the neuroblast turns into a glial cell or a neuron.

The process whose specific outcome is the progression of a neuron over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell.

The process in which the migration of a dendrite is directed to a specific target site in response to a combination of attractive and repulsive cues.

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

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.

The process in which the anatomical structures of a leg derived from an imaginal disc are generated and organized. A leg is a limb on which an animal walks and stands. An example of this is found in Drosophila melanogaster.

The process whose specific outcome is the progression of a chaeta over time, from its formation to the mature structure. A chaeta is a sensory multicellular cuticular outgrowth of a specifically differentiated cell.

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

The process whose specific outcome is the progression of the compound eye over time, from its formation to the mature structure. The compound eye is an organ of sight that contains multiple repeating units, often arranged hexagonally. Each unit has its own lens and photoreceptor cell(s) and can generate either a single pixelated image or multiple images, per eye.

Any process that decreases the rate, frequency, or extent of dauer larval development, the process whose specific outcome is the progression of the dauer larva over time, through the facultative diapause of the dauer (enduring) larval stage, with specialized traits adapted for dispersal and long-term survival, with elevated stress resistance and without feeding.

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.
