Prophase:
Prophase DNA strands become visible as they twist upon themselves and can be seen under the microscope as paired chromatids
Metaphase:
Metaphase Centrioles become visible and begin to migrate to the poles of the cell
Spindle begins to form
Anaphase:
Anaphase Spindle has formed across the cell between the centrioles
Chromatids line up in the middle of the spindle
Telophase:
Telophase Chromatids split apart and begin to migrate to opposite ends of the cell
New nuclear membrane forms
