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.

The aggregation, arrangement and bonding together of a set of components to form the kinetochore, a multisubunit complex that is located at the centromeric region of DNA and provides an attachment point for the spindle microtubules.

The process in which copies of the 2-micrometer plasmid, found in fungi such as Saccharomyces, are distributed to daughter cells upon cell division.

Any process in which a protein is transported to, or maintained at, CENP-A containing chromatin.

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.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the microtubule spindle during a mitotic cell cycle.

The process whose specific outcome is the progression of an embryo over time, from zygote formation until the end of the embryonic life stage. The end of the embryonic life stage is organism-specific and may be somewhat arbitrary; for mammals it is usually considered to be birth, for insects the hatching of the first instar larva from the eggshell.

Any process that stops, prevents, or reduces the frequency, rate or extent of centrosome separation.

The aggregation, arrangement and bonding together of a set of components to form the kinetochore, a multisubunit complex that is located at the centromeric region of DNA and provides an attachment point for the spindle microtubules.

The directed movement of a protein to a specific location on a chromosome.

The directed movement of a protein to a specific location on a chromosome.

Any process in which a protein is transported to, or maintained at, the centromeric region of a chromosome.

The aggregation, arrangement and bonding together of a set of components to form the spindle that contributes to the process of mitosis.

The process in which genetic material, in the form of nuclear chromosomes, is organized into specific structures and then physically separated and apportioned to two or more sets. Nuclear chromosome segregation begins with the condensation of chromosomes, includes chromosome separation, and ends when chromosomes have completed movement to the spindle poles.

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

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

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 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.

A plasmid commonly found in Saccharomyces, inherited in a non-Mendelian manner and often present in 100-400 copies.

A form of nucleosome located only at the centromere, in which the histone H3 is replaced by the variant form CENP-A (sometimes known as CenH3).

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.

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

The region of a condensed 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.

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