During Metaphase, what happens to the chromosomes?

Explanation:
During metaphase, chromosomes position themselves along the cell’s equator, the metaphase plate, with sister chromatids held together at the centromeres and attached to spindle fibers from opposite poles. This arrangement ensures that when separation begins in the next phase, each new nucleus will receive an identical set of chromosomes. The nuclear envelope has already broken down earlier and will reform later, and DNA has already been duplicated during S phase before mitosis starts. So the key idea here is that chromatids line up in the middle.
