ANAPHASE

Spindle fibers shorten; the kinetochores separate and the paired centromeres in each distinct chromosome begin to move apart to the cell poles. Once the paired sister chromatids separate from one another, each is considered a "full" chromosome. They are referred to as daughter chromosomes. Through the spindle apparatus, the daughter chromosomes move to the poles at opposite ends of the cell. At the end of anaphase, each pole contains a complete compilation of chromosomes.
