1. Cell Cycle Review

2. The Steps in the Cell Cycle

4. Building Content Connections: Cancer and Cell Division

5. Cancer  Mitosis out of control! 1.Uncontrolled division / mitosis of cells 2.Cancer cells invade surrounding tissue 3.Disrupt normal functions

7. Common Causes of Cancer 1.Environmental Factors – Tobacco – Smog / air pollution – Chemical exposure 2.UV Radiation 3.Viruses 4.Genetics / Heredity

8. Targets for Cancer Research Cell division / mitosis Causes Treatments

10. Cell Differentiation  How does it all begin?

11. Cell Differentiation Process where a non-specific cell becomes specialized into a specific cell type. Begins with stem cells

12. Stem Cells Basic cells that can differentiate to produce a variety specialized cells Can also divide through mitosis to make more stem cells

13. Cell Differentiation What does NOT change? DNA stays the same What DOES change? Physical characteristics of the cell Response to environment Composition of proteins within the cell
