3. Predict whether functional ?-galactosidase and Permease will be produced by the following E. coli strains under the conditions noted. The diploid genotypes represent F' (lac) strains. Use + to indicate that the enzyme is produced, and 0 to indicate that the enzyme is not produced. 8 pts | | ?-gal + lactose | ?-gal - lactose | Permease + lactose | Permease - lactose | | :--- | :---: | :---: | :---: | :---: | | I?

Predict whether ̢-galactosidase (̢-gal) will be produced by the following E. coli strains under the conditions noted. The diploid genotypes represent F' (lac) strains. For each strain, use a plus sign (+) to indicate that ̢-gal is synthesized, and a minus sign (0) to indicate that the ̢-gal is not synthesized in both the absence and presence of lactose (list your answers in like this example - #11 0 and +). In this scenario, glucose is NOT present in the medium: Genetic Strain of E. coli Bacteria Lactose Absent Lactose Present 1. I+ P+ O+ Z+ 2. IS P+ O+ Z+ 3. I+ P+ OC Z+ 4. I- P+ OC Z+ 5.

In each of the following cases, determine whether ̠-Galactosidase and Permease would be produced by the lac operon in the presence and absence of lactose as an inducer. Write + if the enzyme is produced and – if the enzyme is not produced.
