The MTOC is a major site of microtubule nucleation and can be visualized in cells by immunohistochemical detection of γ-tubulin.
WebThe spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. WebThe mitotic spindle is a structure that forms during cell division and separates duplicated chromosomes. In eukaryotic cells, the mitotic apparatus is composed of two centrosomes and spindle microtubules ( Figure 43.9 ). The centrosome is 1–2 μm in diameter. Each centrosome is composed of two centrioles of approximately 20 nm in diameter ...
