Mitosis

• In the nucleus of most body cells you have two sets of chromosomes arranged as 23 matching pairs of chromosomes, these cells are described as diploid. To make new new cells the body carries out cell division called mitosis.
• 1. Pophase: the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division.
• 2. Prometaphase: The stage in mitotic or meiotic nuclear division, following prophase and preceding metaphase, during which the condensed chromosomes become sequentially attached at their kinetochores to the spindle microtubules.
• 3. Metaphase: the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibres.
• 4. Anaphase: the third stage of cell division, between metaphase and telophase, during which the chromosomes move away from one another to opposite poles of the spindle.
• 5. Telophase and Cytokinesis - The nuclear membrane reforms and the cytoplasm divides into two cells. Ready to start again.
