During which stage do chromatids separate and move toward opposite poles?

Explanation:
During cell division, the stage where sister chromatids separate and are pulled toward opposite ends of the cell is the phase when the centromeres split and the chromatids are moved apart by shortening microtubules attached to kinetochores. This action pulls each chromatid toward opposite poles, so each new daughter cell will receive its own set of chromosomes. Earlier stages involve chromosomes condensing and lining up, while later stages involve the chromosomes arriving at the poles and the cell completing division.
