The Cell Cycle

• Interphase
• Cell Growth and Preparation for Division
• Mitosis
• Division of the Nucleus and its DNA
• Cytokinesis
• Division of the Cytoplasm

3
Interphase

• Gap 1
• Cell Growth
• Synthesis
• DNA Replication
• Gap 2
• Organelle Replication

4
Mitosis

• Prophase
• Metaphase
• Anaphase
• Telophase

5
Prophase

• During this phase, DNA in the form of Chromatin
  condenses into Chromosomes
• The Nuclear Membrane disappears

6
Metaphase

• During this phase, Chromosomes line up at the
  Equator of the Cell
• Centrioles migrate to the poles as Spindle Fibers
  attach to the Centromeres of the Chromosomes

7
Anaphase

• During this phase, the Chromosomes separate, with
  the aid of the Spindle Fibers, and move toward
  the poles of the Cell

8
Telophase

• During this phase, the Chromosomes reach the
  poles of the Cell
• There they begin to uncoil into Chromatin, and
  the Nuclear Membrane reforms

Cytokinesis

• During this phase, the Cell Membrane constricts
  dividing the Cell into two fairly identical Cells
