Inquiry Exercise 21 - Identifying a factor that changes phenotype - The Griffith experiment Redux

Challenge:  To identify the factor that confers resistance to ampicillin.

Students are provided with almost identical bacterial strains that only differ in their sensitivity to ampicillin.  Students review classic experiments on the factors that confer phenotype. They then design experiments to isolate and  confirm the function of factors that militate resistance to ampicillin.
