Metaphase
During metaphase, sister chromatids align forming the metaphase plate. The first two panels show events early in this process as the chromatids migrate to the central region of the cell. The third panel shows a fully formed metaphase plate with its mitotic spindle composed of microtubules. Both centrosomes are also visible at the points where the microtubules converge.
