For each of the E.coli strains shown below, indicate whether production of functional β-galactosidase is constitutive (enzyme is made all the time), inducible (enzyme is only made when lactose is present) or inactive (functional enzyme is not present under any condition). Definitions: I+ : wild-type lac repressor I- : non-functional lac repressor Is : super-repressor that cannot be removed from the operator under any circumstances O+: wild-type operator OC: mutant operator that cannot be bound by any repressor (not even the super-repressor) Z+: wild-type gene for β-galactosidase Z- : mutant gene for β-galactosidase that produces a non-functional enzyme Please watch your spelling! Write inducible, constitutive or inactive in the boxes next to strain information. plasmid I+ OC Z- / chromosome I- O+ Z+ [1] plasmid IS OC Z- / chromosome I- O+ Z+ [2] plasmid I+ Oc Z+ / chromosome I+ O+ Z+ [3] plasmid I+ O+ Z+ / chromosome I- O+ Z+ [4] plasmid IS O+ Z- / chromosome I+ OC Z+ [5]
