In  anaphase,  sister  chromatids
   separate from each other (disjoin) and migrate to opposite poles.

   Each centromere divides, resulting in two kinetochores.

   Each chromatid is attached to one kinetochore, and is pulled to a pole
   by shortening the spindle fibers to which the chromatid is attached.

   The separated sister chromatids are called daughter chromosomes.
