Tobacco Induced Mutations
(7-12 grade toxicology curriculum)



Students expose bacteria to 4 different concentrations of tobacco extract and observe the dose-response mutagenic effect on the bacteria. The bacteria change from red to white when they mutate. Photos of this change can be seen online here.

Since mutations are an important precursor to cancer, this lab would work well in a unit on cancer or genetics. It would also complement discussion about toxicology or lab techniques commonly used in biological sciences.
