  2. Centrosome cycle - Wikipedia

    en.wikipedia.org/wiki/Centrosome_cycle

    However, the two centrioles are of different ages. This is because one centriole originates from the mother cell while the other is replicated from the mother centriole during the cell cycle. It is possible to distinguish between the two preexisting centrioles because the mother and daughter centriole differ in both shape and function. [5]

  3. Centrosome - Wikipedia

    en.wikipedia.org/wiki/Centrosome

    The centrosome is copied only once per cell cycle, so that each daughter cell inherits one centrosome, containing two structures called centrioles. The centrosome replicates during the S phase of the cell cycle. During the prophase in the process of cell division called mitosis, the centrosomes migrate to opposite poles of the cell. The mitotic ...

    3D rendering of centrioles showing the triplets. In cell biology a centriole is a cylindrical organelle composed mainly of a protein called tubulin. [1] Centrioles are found in most eukaryotic cells, but are not present in conifers (), flowering plants (angiosperms) and most fungi, and are only present in the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and Ginkgo.

  9. Cell death - Wikipedia

    en.wikipedia.org/wiki/Cell_death

    Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
