Its function is to segregate chromosomes during cell division (either mitosis or meiosis) to the daughter cells.
WebMTOCs 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. The MTOC is a major site of microtubule nucleation and can be visualized in cells by immunohistochemical detection of γ-tubulin. WebComposed largely of microtubules and chromosomes, the spindle also contains numerous proteins whose roles include biochemical and biophysical regulation of mitosis. Given the transient, dynamic nature of the spindle, the light microscope continues to be the main tool employed to unlock its mysteries.
