Involves the splitting of the centriole
Centrioles are involved in the organization of the mitotic spindle and in the completion of cytokinesis. Centrioles were previously thought to be required for the formation of a mitotic spindle in animal cells. However, more recent experiments have demonstrated that cells whose centrioles have been … Meer weergeven In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells, but are not present in conifers (Pinophyta), flowering plants (angiosperms) … Meer weergeven The centrosome was discovered jointly by Walther Flemming in 1875 and Edouard Van Beneden in 1876.

The position of the centriole determines the position of the nucleus and plays a crucial role in the spatial arrangement of the cell. Meer weergeven In flagellates and ciliates, the position of the flagellum or cilium is determined by the mother centriole, which becomes the basal body. … Meer weergeven Before DNA replication, cells contain two centrioles, an older mother centriole, and a younger daughter centriole.

Webby analysis of dividing stem cells in the Drosophila male germ line, in which the mitotic spindle is always oriented such that the older centriole is anchored on the side of the cell adjacent to the stem-cell niche [34]. Similar bias in mother centriole position is seen in radial glial progenitor cells in the mouse [35]. Remarkably, following ...

WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts ...
