Cell Cycle Review
The Steps in the Cell Cycle
Building Content Connections: Cancer and Cell Division
Cancer Mitosis out of control! 1.Uncontrolled division / mitosis of cells 2.Cancer cells invade surrounding tissue 3.Disrupt normal functions
Common Causes of Cancer 1.Environmental Factors – Tobacco – Smog / air pollution – Chemical exposure 2.UV Radiation 3.Viruses 4.Genetics / Heredity
Targets for Cancer Research Cell division / mitosis Causes Treatments

Cell Differentiation How does it all begin?
Cell Differentiation Process where a non-specific cell becomes specialized into a specific cell type. Begins with stem cells
Stem Cells Basic cells that can differentiate to produce a variety specialized cells Can also divide through mitosis to make more stem cells
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
