Mitosis

• Mitosis is a type of cell division done by most of your body cells and it's really important for your cells to divide
• If cells didn't divide, you wouldn't grow
• Mitosis


  The process that allows cells to grow and repair damage
• Mitosis is not the process that makes sperm or egg cells, that is called meiosis
• Mitosis


  Produces identical body cells
• Cells are not dividing all the time, they spend most of their time in interphase
• Cancer


  Uncontrolled cell growth, or uncontrolled mitosis
• Nucleus


  Organelle that holds the cell's DNA
• Chromosomes


  Condensed units of DNA and protein found in the nucleus
• Humans have 46 chromosomes in their body cell nuclei
• Mitosis


  1. Prophase

  2. Metaphase

  3. Anaphase

  4. Telophase
• Spindles help move the chromosomes to the opposite ends of the cell during anaphase
• Cytokinesis is responsible for the final separation into two cells after the mitosis stages
• Understanding mitosis is important for understanding growth, repair, and cancer
