Question

Quizplus · Accepted Answer

The spindle begins to form during prophase of mitosis, when microtubules begin to radiate out from the centrosomes at opposite ends of the cell. During metaphase, the spindle is fully formed and the chromosomes align along the middle of the spindle. In anaphase, the spindle fibers shorten, pulling the sister chromatids apart to opposite sides of the cell. In telophase, the spindle disassembles and the nuclear envelope reforms.
