The Cell Cycle
What are the 3 phases of the cell cycle?
What are the 4 phases of Mitosis?
What is differentiation?
The Cell Cycle
• Cell growth and division
• 3 phases:
1. Interphase
2. Mitosis
3. Cytokinesis
Phase 1
• INTERPHASE
• cells grow
• copy their DNA (replication)
• prepare to divide
Phase 2
• MITOSIS
• Nucleus divides into 2
• 4 phases of mitosis:
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase

Phase 3
• CYTOKINESIS
• cytoplasm divides
• two new cells are formed
• “daughter cells”
• They are identical copies
Differentiation
• Process where cells change in structure
• Become specialized
• Change function
Brain Cell
Red Blood Cells
White Blood Cells
Stem Cells
• Can turn into other cells
o
Ex: stem cell  blood cell
• Only happens when body needs to replace cells
Embryonic stem cell
