Look again at your four plates. Do you observe some E. coli growing on the LB plates
which do not contain ampicillin/arabinose?
From your results, can you tell if these bacteria are ampicillin resistant by looking at
them on the LB plate? Explain your answer.

How would you change the bacteria's environment to best tell if they are ampicillin
resistant?
What two factors must be present in the bacteria's environment for you to see the
green color? (Hint: one factor is in the plate and the other factor is in how you look
at the bacteria).
What do you think each of the two environmental factors you listed above are
doing to cause the genetically transformed bacteria turn green?
