List the phases of Mitosis and the defining features of each phase.
Prophase: Cell looks normal, spindle fibers are visible

Metaphase: Chromatids are lined up in the middle of the cell on the metaphase plate
Anaphase: Chromatids are being pulled to the opposite poles of the cell
Telophase & Cytokinesis: Nuclear envelope reforms and two new cells are formed
