Introduction to mitosis

  1. 1. Introduction to Mitosis<br />CLASS NOTES<br />Wed., Sept. 22, 2010<br />
  2. 2. Why do cells divide?<br />Cells divide to create new cells!<br />For example, red blood cells are being produced to replace worn out blood cells at a rate of 10 million to 15 million EACH SECOND!<br />
  3. 3. How are these new cells created?<br />Each cell has a life cycle, just like a living organism (e.g. human)<br />Like an organism, cells have different stages of life<br />E.g. You are in a stage called adolescence, where a lot of growth and development occurs<br />Most of the life of a cell is spent in a stage called interphase<br />
  4. 4. The Cell Cycle<br />Interphase<br />3 stages:<br />Cell grows<br />Cell makes a copy of its genetic information<br />Cell grows and prepares for cell division (mitosis)<br />
  5. 5. Mitosis<br />Cells divide in two steps:<br />Nucleus of cell divides (mitosis)<br />Cytoplasm divides <br />Mitosis is the process in which the nucleus divides to form TWO identical nuclei<br />Mitosis has 4 stages:<br />Prophase<br />Metaphase<br />Anaphase<br />Telophase<br />
