(kih-net-oh-kor) [Gk. kinetikos, putting in motion + choros, chorus] A specialized region on the centromere that links each sister chromatid to the mitotic spindle.

A structure that attaches laterally to the centromere of a chromosome; it is the site of chromosome tubule attachment.

The complex of proteins which mediates the interaction between microtubules and chromosomes.

A three-layer protein structure located at or near the centromere of each mitotic chromosome from which microtubules (kinetochore fibers) extend toward the spindle poles of the cell; plays an active r [..]

Large Multiprotein Complexes that bind the Centromeres of the Chromosomes to the Microtubules of the mitotic spindle during Metaphase in the Cell Cycle.

See centromere.

A condensed protein structure on chromatids where spindle fibers attach during mitosis and meiosis.

a structure which attaches the chromosome to the spindle apparatus and assists in segregation of chromatids during mitosis.

A pair of structures adjacent to the chromosomal centromere to which spindle microtubules attach.

The chromosomal attachment point for the spindle fibers located within the centromeres.

A structure formed adjacent to the centromere of a condensed chromosome that allows the chromosome to attach to microtubules of the meiotic or mitotic spindle.
