  MITOSIS
• 5.
  Mitosis The processof cell division which results in the production of two “daughter” cells from a single parent cell. The daughter cells are identical to one another and to the original parent cell.

  The Stages ofMitosis

  1st: Interphase Thecell prepares for division • Chromosomes are copied Centromere
• 8.

  Prophase The cellprepares for division • DNA condenses to form chromosomes • Centrioles appear • Spindle fibers form between the poles
• 10.

  Metaphase The cellprepares chromosomes for division • Spindle fibers attach to the chromatids • Chromosomes line in the midline of the cell (the equator)
• 12.

  Anaphase The chromosomesdivide • Chromatids separate and begin to move to opposite ends of the cell.
• 14.

  Telophase • Twonew nuclei form • Chromosomes appear as chromatin (threads rather than rods) • Mitosis ends

  Cytokinesis Two daughtercells are formed • Cell membrane pinches create two daughter cells – each with its own nucleus and identical chromosomes
