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

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

Ordering of successions of nucleosomes into regular arrays so that nucleosomes are positioned at defined distances from one another.

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

The modification of histone H3 by addition of three methyl groups to lysine at position 27 of the histone.

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

Any process that results in the specification, formation or maintenance of the physical structure of eukaryotic chromatin.

The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.

Any process that activates or increases the frequency, rate, extent or direction of cell growth.

Any process involved in maintaining the structure and integrity of a protein and preventing it from degradation or aggregation.

Any process that activates or increases the frequency, rate or extent of the covalent addition of a methyl group to the lysine at position 9 of histone H3.

The directed movement of a protein to a part of a chromosome that is organized into chromatin.

The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.

Any process that activates or increases the frequency, rate or extent of receptor mediated endocytosis, the uptake of external materials by cells, utilizing receptors to ensure specificity of transport.

The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.

The process in which the sperm binds to the zona pellucida glycoprotein layer of the egg. The process begins with the attachment of the sperm plasma membrane to the zona pellucida and includes attachment of the acrosome inner membrane to the zona pellucida after the acrosomal reaction takes place.

The process whose specific outcome is the progression of the muscle over time, from its formation to the mature structure. The muscle is an organ consisting of a tissue made up of various elongated cells that are specialized to contract and thus to produce movement and mechanical work.

The progressive compaction of dispersed interphase chromatin into threadlike chromosomes prior to mitotic or meiotic nuclear division, or during apoptosis, in eukaryotic cells.

Any process involved in the controlled movement of a flagellated sperm cell.

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 condensed form of chromatin, occurring in the nucleus during interphase, that stains strongly with basophilic dyes. The DNA of heterochromatin is typically replicated at a later stage in the cell-division cycle than euchromatin.

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

The dispersed less dense form of chromatin in the interphase nucleus. It exists in at least two forms, a some being in the form of transcriptionally active chromatin which is the least condensed, while the rest is inactive euchromatin which is more condensed than active chromatin but less condensed than heterochromatin.

In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

The external part of the cell wall and/or plasma membrane.

Any small, fluid-filled, spherical organelle enclosed by membrane.

The ordered and organized complex of DNA and protein that forms regions of the chromosome that are being actively transcribed.

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

A complex comprised of DNA wound around a multisubunit core and associated proteins, which forms the primary packing unit of DNA in the nucleus into higher order structures.

A complex comprised of DNA wound around a multisubunit core and associated proteins, which forms the primary packing unit of DNA in the nucleus into higher order structures.

A highly compacted molecule of DNA and associated proteins resulting in a cytologically distinct nuclear chromosome.

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.
