  2. Spindle apparatus - Wikipedia

    en.wikipedia.org/wiki/Spindle_apparatus

    In cell biology, the spindle apparatus is the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis , a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis , a process ...

    en.wikipedia.org/wiki/Aster_(cell_biology)

    This diagram depicts the organization of a typical mitotic spindle found in animal cells. Chromosomes are attached to kinetochore microtubules via a multiprotein complex called the kinetochore . Polar microtubules interdigitate at the spindle midzone and push the spindle poles apart via motor proteins.

  5. Microtubule organizing center - Wikipedia

    en.wikipedia.org/wiki/Microtubule_organizing_center

    The microtubule-organizing center (MTOC) is a structure found in eukaryotic cells from which microtubules emerge. MTOCs have two main functions: the organization of eukaryotic flagella and cilia and the organization of the mitotic and meiotic spindle apparatus, which separate the chromosomes during cell division.

  6. Cleavage furrow - Wikipedia

    en.wikipedia.org/wiki/Cleavage_furrow

    This spindle apparatus consists of microtubules, microfilaments and a complex network of various proteins. During metaphase, the chromosomes line up using the spindle apparatus in the middle of the cell along the equatorial plate. The chromosomes move to opposite poles during anaphase and remain attached to the spindle fibers by their centromeres.

  7. Kinetochore - Wikipedia

    en.wikipedia.org/wiki/Kinetochore

    The spindle checkpoint, or SAC (for spindle assembly checkpoint), also known as the mitotic checkpoint, is a cellular mechanism responsible for detection of: correct assembly of the mitotic spindle; attachment of all chromosomes to the mitotic spindle in a bipolar manner; congression of all chromosomes at the metaphase plate.

  8. Centralspindlin - Wikipedia

    en.wikipedia.org/wiki/Centralspindlin

    Centralspindlin is required for the assembly of the mitotic spindle [3] as well as for microtubule bundling and anchoring of midbody microtubules to the plasma membrane. [ 1 ] [ 2 ] This complex is also implicated in tethering the spindle apparatus to the plasma membrane during cytokinesis [ 4 ] This interaction permits cleavage furrow ingression.

  9. Cell division - Wikipedia

    This breakdown then allows the spindle apparatus growing from the centrosome to attach to the kinetochores on the sister chromatids. Stable attachment of the spindle apparatus to the kinetochores on the sister chromatids will ensure error-free chromosome segregation during anaphase. [24] Prometaphase follows prophase and precedes metaphase.
