Question
1. Draw a diagram of the lac operon, labeling all of its structural genes and regulatory DNA sequences.
2. Identify the function of the proteins encoded by the lac operon.
3. Identify the lac operon as an inducible and/or repressible operon and identify its corresponding inducer/co-repressor.
6. Identify what conditions must exist for maximum expression of the lac operon and explain why these conditions are needed.
7. Identify the protein that is encoded by the lacI gene AND explain what constitutive expression means. Why is it important that the lacI gene is constitutively expressed?
