1. The Stages of Cell Division BY: MARK DESILVA

2. Prophase/ Pro Metaphase Anaphase Telophase The Stages of Mitosis

3. Prophase/ Prometaphase Chromatin condenses into dicrete Chromosomes Nucleoli disappear Chromosomes have the two identical sister chromatids Mitotic Spindle begins to form The Centrosomes move away from each other Nuclear Envelope fragments Chromosomes become more condensed

4. Prophase Pictures

5. Metaphase Centrosomes are apposite poles of the cell Chromosomes are at the metaphase plate, that is equidistant between the spindle’s two poles For each chromosome the kinetochores of the sister chromatids are attached to kinetochore microtubules coming from opposite poles

6. Metaphase Pictures

7. Anaphase Shortest Stage of mitosis and only lasts a few minutes Begins when the cohesin proteins are cleaved, allowing the two sister chromatids to part The daughter chromosomes begin moving toward opposite ends of the cell The cell becomes longer and the microtubules lengthen Both ends of the cell have a complete set of chromosomes

9. Telophase Two daughter nuclei form Nucleoli reappear Chromosomes become less dense Any remaining spindle microtubules are depolymerized The Division of one nucleus into two genetically identical nuclei is now complete
