Cells

1. Mitosis

   • Asexual reproduction
   • Growth
   • Repair
   • Replacement
   • 1.Prophase
     • Replicated Chromosomes
     • Supercoil
     • Cenrioles to poles
     • Spindle fibres form
   • 2.Metaphase
     • Chromosomes down equator.
     • Attached to spindle fibres.
   • 3.Anaphase
     • Chromosomes pulled apart
   • 4.Telophase
     • 2 new nuclei form

2. Cell Cycle

   • G1
     • Cell grows
     • Creation of organelles
     • Creation of proteins
   • Synthesis
     • DNA replicates
     • DNA checked for mutations.
   • G2
     • Cell grows proteins for cell division.
   • Mitotic stage
     • Cytokenisis
     • Mitosis
