And the building cytoskeleton are responsible for shaping the cell. And the building blocks of these microtubules are used to grow the mitotic spindle blocks of these microtubules are used to grow the mitotic spindle from the region of the centrosomes.from the region of the centrosomes.

Some mitotic spindle Fibers stretch out from the see a nucleus. Some mitotic spindle Fibers stretch out from the Centrosomes and attach to Kinetochores. Other spindle Fibers Centrosomes and attach to Kinetochores. Other spindle Fibers stretch out but instead of attaching to the chromosomes they stretch out but instead of attaching to the chromosomes they overlap each other at the center of the cell.overlap each other at the center of the cell.
