M Phase (Cell Division Phase)
1. Prophase: Chromosomes become visible, centrioles begin moving to opposite ends of the cell
2. Metaphase: Spindle fibers align the chromosomes at the equatorial plate or along the middle of the cell
3. Anaphase: Paired chromosomes or sister chromatids separate and move to opposite sides of the cell
4. Telophase: Chromatids arrive at opposite poles of cell, and new nuclear membranes form around the daughter nuclei (karyokinesis) to form daughter cells as the cytoplasm divides into two (cytokinesis)
