Question

Quizplus · Accepted Answer

Polar microtubules overlap in the center of the spindle, helping to stabilize the structure of the mitotic spindle during cell division. They do not attach directly to kinetochores or the contractile ring, nor do they pull kinetochores poleward; those functions are associated with kinetochore microtubules and motor proteins.
