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.

Repression of transcription of telomeric DNA by altering the structure of chromatin.

Repression of transcription at silent mating-type loci by alteration of the structure of chromatin.

Repression of transcription of centromeric DNA by altering the structure of chromatin.

The cell cycle process in which replicated homologous chromosomes are organized and then physically separated and apportioned to two sets during the mitotic cell cycle. Each replicated chromosome, composed of two sister chromatids, aligns at the cell equator, paired with its homologous partner. One homolog of each morphologic type goes into each of the resulting chromosome sets.

Repression of transcription of ribosomal DNA by altering the structure of chromatin.

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

The cell cycle process in which the sister chromatids of a replicated chromosome are joined along the entire length of the chromosome, from their formation in S phase through metaphase during a mitotic cell cycle. This cohesion cycle is critical for high fidelity chromosome transmission.

The conversion of a single-cell organism from one mating type to another by the precise replacement of a DNA sequence at the expressed mating type locus with a copy of a sequence from a donor locus.

The conversion of the mating-type locus from one allele to another resulting from the recombinational repair of a site-specific double-strand break at the mating-type locus with information from a silent donor sequence. There is no reciprocal exchange of information because the mating-type locus copies information from the donor sequence and the donor sequence remains unchanged.

The process that determines which donor locus a cell uses, in preference to another, in mating type switching.

Any process in which a protein is transported to, and/or maintained in, a specific location at the level of a cell. Localization at the cellular level encompasses movement within the cell, from within the cell to the cell surface, or from one location to another at the surface of a cell.

A cellular protein complex localization that acts on a chromosome passenger complex; as a result, the complex is transported to, or maintained in, a specific location at the kinetochore. A chromosome passenger complex is a protein complex that contains the BIR-domain-containing protein Survivin, Aurora B kinase, INCENP and Borealin, and coordinates various events based on its location to different structures during the course of mitosis.

Repression of transcription of DNA at the outer repeat region of a regional centromere by altering the structure of chromatin.

Nuclear heterochromatin that is located adjacent to the CENP-A rich centromere 'central core' and characterized by the modified histone H3K9me3.

The microtubule organizing center that forms as part of the mitotic cell cycle; functionally homologous to the animal cell centrosome.

The region of a condensed nuclear chromosome that includes the centromere and associated proteins, including the kinetochore. 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 in the nucleus.

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.

Heterochromatin that is located adjacent to the CENP-A rich centromere 'central core' and characterized by the modified histone H3K9me3.

Heterochromatic regions of the chromosome found at silenced mating-type loci.

Heterochromatic regions of the chromosome found at silenced mating-type loci.

The portion of the centromeric region of a chromosome that flanks the core region, encompassing repeated regions of a chromosome centromere and the proteins that bind to it.

Heterochromatic regions of the chromosome found at the subtelomeric regions of a chromosome in the nucleus.

Heterochromatic regions of the chromosome found at the subtelomeric regions of a chromosome in the nucleus.
