Interphase

• G1 Growth
• S DNA Replication
• G2 Growth
• Centrioles with asters

9
Prophase

• Chromatin to chromosomes
• Nucleus and Nucleolus disappear
• Chromosomes
• Two chromatids with centromere
• Kinetochore
• Spindle apparatus

10
Metaphase

• Centrosomes at opposite poles
• Chromosomes line up on metaphase plate

11
Anaphase

• Chromosomes pulled apart become daughter
  chromosomes

12
Telophase and Cytokinesis

• Reverse of Prophase
• Cytokinesis
• Animal cells
• Cleavage Furrow
