Sister Chromatids become visible as the nucleus breaks down, the first phase of Mitosis.	Prophase
Sister Chromatids meet in the middle, the second phase of Mitosis.	Metaphase
Sister Chromatids are moved apart by Spindle Fibers made by centrosomes organelles, the second phase of Mitosis.	Anaphase
Two new Nuclei form around each cluster of chromosomes, the fourth phase of Mitosis.	Telophase
