Spindle fibers are attached to centrosomes
WebThe chromosomes then migrate to the equatorial plane where they attach to one of the spindle fibers. In animal cells, spindle formation occurs by centrosomes, which are composed of twin centrioles at right angles surrounded by amorphous material. The centrosome is the major microtubule-organizing center during interphase. WebThe two centrosomes attach themselves to the opposite poles of the nucleus. Once the nuclear membrane dissolves, they form spindles, connected to each other by the formation of spindle fibers between them. …
