Compensating for the variation in the unpaired sex chromosome:autosome chromosome ratios between sexes by activation or inactivation of genes on one or both of the sex chromosomes.

Compensating for the variation in the unpaired sex chromosome:autosome chromosome ratios between sexes by activation or inactivation of genes on one or both of the sex chromosomes.

Compensating for the variation in the unpaired sex chromosome:autosome chromosome ratios between sexes by activation or inactivation of genes on one or both of the sex chromosomes.

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

Compensating for the two-fold variation in X-chromosome:autosome ratios between sexes by a global hyperactivation of all, or most of, the genes on the X-chromosome in the heterogametic sex, leading to a two-fold increase in gene expression from this chromosome. An example of this is found in Drosophila melanogaster.

The aggregation, arrangement and bonding together of proteins on DNA to form the complex that mediates dosage compensation on the X chromosome of the heterogametic sex, ultimately resulting in a two-fold increase in transcription from this chromosome. An example of this is found in Drosophila melanogaster.

Any process that activates or increases the frequency, rate or extent of heterochromatin formation.

The process in which interchain hydrogen bonds between two strands of DNA are broken or 'melted', generating a region of unpaired single strands.

The process during wing vibration where the male insect produces a species-specific acoustic signal called a love song.

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

Long distance growth of a single axon process involved in cellular development.

Any process that modulates the frequency, rate or extent of mRNA processing, those processes involved in the conversion of a primary mRNA transcript into a mature mRNA prior to its translation into polypeptide.

Any process that activates or increases the frequency, rate or extent of DNA topoisomerase (ATP-hydrolyzing) activity.

Any process that modulates the frequency, rate or extent of cytoplasmic translation.

A chromosome that encodes the nuclear genome and is found in the nucleus of a eukaryotic cell during the cell cycle phases when the nucleus is intact.

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

The sex chromosome present in both sexes of species in which the male is the heterogametic sex. Two copies of the X chromosome are present in each somatic cell of females and one copy is present in males.

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 structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information.

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.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

An RNA-protein complex localized to the X chromosome of males where it is required for the hyper-transcriptional activation of the X chromosome. An example of this is found in Drosophila melanogaster.

An RNA-protein complex localized to the X chromosome of males where it is required for the hyper-transcriptional activation of the X chromosome. An example of this is found in Drosophila melanogaster.

A histone acetyltransferase complex that catalyzes the acetylation of a histone H4 lysine residue at position 16. In human, it contains the catalytic subunit MOF, and MSL1, MSL2 and MSL3.

A macromolecular complex containing both protein and RNA molecules.
