The cell cycle process in which the sister chromatids of a replicated chromosome become tethered to each other.

The cell cycle process in which the sister chromatids of a replicated chromosome become tethered to each other.

The cell cycle process in which the sister chromatids of a replicated chromosome become tethered to each other.

The joining of the sister chromatids of a replicated chromosome along the entire length of the chromosome that occurs during meiosis in a male.

The joining of the sister chromatids of a replicated chromosome along the entire length of the chromosome that occurs during meiosis in a female.

The meiotic cell cycle process where side by side pairing and physical juxtaposition of homologous chromosomes is created during meiotic prophase. Synapsis begins when the chromosome arms begin to pair from the clustered telomeres and ends when synaptonemal complex or linear element assembly is complete.

The cell cycle process in which the synaptonemal complex is formed. This is a structure that holds paired chromosomes together during prophase I of meiosis and that promotes genetic recombination.

The process by which an organism or tissue maintains a population of stem cells of a single type. This can be achieved by a number of mechanisms: stem cell asymmetric division maintains stem cell numbers; stem cell symmetric division increases them; maintenance of a stem cell niche maintains the conditions for commitment to the stem cell fate for some types of stem cell; stem cells may arise de novo from other cell types.

Any process that stops, prevents, or reduces the frequency, rate or extent of DNA endoreduplication.

Any process that stops, prevents, or reduces the frequency, rate or extent of DNA endoreduplication.

Any process in which a protein is transported to, or maintained at, a specific location on a chromosome.

Progression through the phases of the meiotic cell cycle, in which canonically a cell replicates to produce four offspring with half the chromosomal content of the progenitor cell via two nuclear divisions.

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

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

The region of a chromosome that includes the centromeric DNA and associated proteins. In monocentric chromosomes, this region corresponds to a single area of the chromosome, whereas in holocentric chromosomes, it is evenly distributed along the chromosome.

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

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

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

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

Extra-nucleolar nuclear domains usually visualized by confocal microscopy and fluorescent antibodies to specific proteins.

A proteinaceous scaffold found between homologous chromosomes during meiosis. It consists of 2 lateral elements and a central element, all running parallel to each other. Transverse filaments connect the lateral elements to the central element.

A cohesin complex that mediates sister chromatid cohesion during meiosis; has a subunit composition distinct from that of the mitotic cohesin complex.

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

A proteinaceous scaffold found between homologous chromosomes during meiosis. It consists of 2 lateral elements and a central element, all running parallel to each other. Transverse filaments connect the lateral elements to the central element.

A proteinaceous core found between sister chromatids during meiotic prophase.

A structural unit of the synaptonemal complex that spans the regions between the lateral elements and connects them.

The nucleus of a male germ cell, a reproductive cell in males.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

A cohesin complex that mediates sister chromatid cohesion during meiosis; has a subunit composition distinct from that of the mitotic cohesin complex.

A cohesin complex that mediates sister chromatid cohesion in the nucleus during meiosis; has a subunit composition distinct from that of the mitotic cohesin complex.
