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
