Anaphase is a phase of mitosis that follows interphase, prophase and metaphase. There are several key steps that occur in anaphase that allow the cell to progress through mitosis. First the sister chromatids that were previously attached to each other by the centromere will begin to separate and will start to move to opposite ends of the cell. The cell will also begin to elongate to prepare for division. The end result of anaphase is one complete set of chromosomes at each pole of the cell so that the final stage of mitosis which is the division of the cell membrane resulting in two separate cells can occur.
