For each region of the lac operon on the F' plasmid, I+ P+ Oc Z− Y+ , determine whether the region is wild type
For each region of the lac operon on the F' plasmid, I+ P+ Oc Z− Y+ , determine whether the region is wild type (that is, it produces a functional protein or it's a correct protein binding sequence) or whether the region is mutated. Select all that apply. Select all that apply. The promoter sequence is correct/functional. The repressor protein is produced. The operator sequence is correct/functional. Beta-galactosidase is produced from the lacZ gene. Permease is produced from the lacY...

The map of the lac operon is:    POZY   The promoter (P) region is the start site of transcription through the binding of RNA polymerase before actual mRNA production. Mutationally altered promoters (P-) cannot bind RNA polymerase. Certain predictions can be made about the effect of P- mutations. Use your predictions and your knowledge of the lactose system to complete the following table. Insert a “+” where an enzyme is produced and a “-“ where no enzyme is produced. The first one...
