The cell cycle process in which centrosome duplication and separation takes place. The centrosome cycle can operate with a considerable degree of independence from other processes of the cell cycle.

The cell cycle process in which a daughter centriole is formed perpendicular to an existing centriole. An immature centriole contains a ninefold radially symmetric array of single microtubules; mature centrioles consist of a radial array of nine microtubule triplets, doublets, or singlets depending upon the species and cell type. Duplicated centrioles also become the ciliary basal body in cells that form cilia during G0.

A cell cycle process by which the cell nucleus divides as part of a meiotic cell cycle in the male germline.

The asymmetric division of cells to produce two daughter cells with different developmental potentials. It is of fundamental significance for the generation of cell diversity.

Mitotic division cycles 10 to 13 of the insect embryo. This is the second phase of the syncytial period where nuclei divide in a common cytoplasm without cytokinesis. The majority of migrating nuclei reach the embryo surface during cycle 10, after which they divide less synchronously than before, and the syncytial blastoderm cycles lengthen progressively.

Self-propelled movement of a cell or organism from one location to another.

The addition of tubulin heterodimers to one or both ends of a microtubule.

The process in which duplicated centrosome components move away from each other. 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.

The assembly of a cilium, a specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface. Each cilium is bounded by an extrusion of the cytoplasmic membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole.

A process in which a protein is transported to, or maintained in, a location within a pericentriolar material.

A network of small fibers that surrounds the centrioles in cells; contains the microtubule nucleating activity of the centrosome.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A cellular organelle, found close to the nucleus in many eukaryotic cells, consisting of a small cylinder with microtubular walls, 300-500 nm long and 150-250 nm in diameter. It contains nine short, parallel, peripheral microtubular fibrils, each fibril consisting of one complete microtubule fused to two incomplete microtubules. Cells usually have two centrioles, lying at right angles to each other. At division, each pair of centrioles generates another pair and the twin pairs form the pole of the mitotic spindle.
