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

Construction of the vitelline membrane portion of a chorion-containing eggshell. An example of this is found in Drosophila melanogaster.

Construction of the chorion portion of the eggshell, which comprises the channels for gas exchange in an insect eggshell.

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.

Any process that stops, prevents, or reduces the frequency, rate or extent of chromatin silencing.

Progression through the phases of the mitotic cell cycle, the most common eukaryotic cell cycle, which canonically comprises four successive phases called G1, S, G2, and M and includes replication of the genome and the subsequent segregation of chromosomes into daughter cells. In some variant cell cycles nuclear replication or nuclear division may not be followed by cell division, or G1 and G2 phases may be absent.

The initial formation of a blastocyst from a solid ball of cells known as a morula.

The process whose specific outcome is the progression of the placenta over time, from its formation to the mature structure. The placenta is an organ of metabolic interchange between fetus and mother, partly of embryonic origin and partly of maternal origin.

The reorganization or renovation of existing blood vessels.

The developmental process in which the heart is generated and organized. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.

The process in which an epicardial cell acquires the specialized structural and/or functional features of a cardiac endothelial cell.

Dynamic structural changes to eukaryotic chromatin occurring throughout the cell division cycle. These changes range from the local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation.

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.

Any process that stops, prevents or reduces the rate or extent of cell proliferation.

Any process that stops, prevents or reduces the rate or extent of cell proliferation.

Any process that stops, prevents or reduces the rate or extent of cell proliferation.

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

The process whose specific outcome is the progression of a cardiac vascular smooth muscle cell over time, from its formation to the mature state.

The differentiation of endothelial cells from progenitor cells that contributes to blood vessel development in the heart, and the de novo formation of blood vessels and tubes.

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 SWI/SNF-type complex that contains a bromodomain containing-protein, such as yeast Rsc1 or Rsc4 or mammalian PB1/BAF180. The RSC complex is generally recruited to RNA polymerase III promoters and is specifically recruited to RNA polymerase II promoters by transcriptional activators and repressors; it is also involved in non-homologous end joining

A SWI/SNF-type complex that contains 8 to 14 proteins, including both conserved (core) and nonconserved components; contains the ATPase product of the Drosophila brm (brahma) or mammalian SMARCA2/BAF190B/BRM gene, or an ortholog thereof.

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.

A multisubunit complex that is located at the centromeric region of DNA and provides an attachment point for the spindle microtubules.

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.

That part of the nuclear content other than the chromosomes or the nucleolus.
