The process whose specific outcome is the progression of the eye over time, from its formation to the mature structure. The eye is the organ of sight.

The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.

The process whose specific outcome is the progression of the haltere over time, from its formation to the mature structure. The haltere is the club-shaped 'balancers' found on each side of the metathorax among the true flies (Diptera). They are the much-modified hind wings.

The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.

The orderly movement of a cell specialized to produce haploid gametes through the embryo from its site of production to the place where the gonads will form.

The modification of histones by addition of methyl groups.

The modification of histones by addition of methyl groups.

The modification of a histone by the addition of an acetyl group.

Any process that activates or increases the frequency, rate or extent of transcription elongation, the extension of an RNA molecule after transcription initiation and promoter clearance by the addition of ribonucleotides, catalyzed by RNA polymerase II.

Any process that activates or increases the frequency, rate or extent of transcription elongation, the extension of an RNA molecule after transcription initiation and promoter clearance by the addition of ribonucleotides, catalyzed by RNA polymerase II.

The modification of histone H3 by the addition of an acetyl group.

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.

The modification of histone H3 by addition of one or more methyl groups to lysine at position 4 of the histone.

The modification of histone H3 by addition of one or more methyl groups to lysine at position 4 of the histone.

The modification of histone H3 by addition of one or more methyl groups to lysine at position 4 of the histone.

A protein complex that possesses histone acetyltransferase activity.

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 type of chromosome in a polyploid cell, formed when multiple copies of homologous chromosomes are aligned side by side to give a giant chromosome in which distinct chromosome bands are readily visible.

A stretch of densely packed chromatin along the polytene chromosome, visible as a morphologically distinct band.

Any protein complex that interacts with RNA polymerase II to increase (positive transcription elongation factor) or reduce (negative transcription elongation factor) the rate of transcription elongation.

A multimeric complex that is able to catalyze the addition of methyl groups to histone proteins.

A protein complex that can methylate lysine-4 of histone H3, and which contains either of the protein subunits MLL1 or MLL2 in human, or equivalent in other species.
