The stage during the mitotic cell division represented in the question is Anaphase. This is the shortest stage of mitosis.

During anaphase, the sister chromatids separate at the centromeres and are pulled to opposite poles of the cell by spindle fibers, ensuring each daughter cell receives a complete set of chromosomes. The separated sister chromatids, now referred to as daughter chromosomes, are pulled towards opposite poles of the cell by the spindle fibers attached to their kinetochores. 

After anaphase, the cell enters telophase where the nuclear envelope reforms around each set of chromosomes, and the cell divides into two daughter cells through cytokinesis.
