Term

mitotic centrosome separation

ID (Ontology)

GO:0007100 (Gene Ontology)

Definition

Separation of duplicated centrosome components at the beginning of mitosis. The centriole pair within each centrosome becomes part of a separate microtubule organizing center that nucleates a radial array of microtubules called an aster. The two asters move to opposite sides of the nucleus to form the two poles of the mitotic spindle.[ ISBN:0815316194 ]
