Answer:
Option (4).
Explanation:
Lac operon is present in E.coli that regulate the metabolism of lactose in the bacteria. Lac Operon consists of three genes : Lac Y, lac Z and lac A, an operator and a promoter.
I+ P+ Oc Z− Y+ / I− P+ O+ Z+ Y− , in this case inducer is present, promoter is present, constitutive region and the gene lac Z and lac Y indicates the Z and Y. The permease enzyme will made in the presence and absence of lactose due to the presence of I+ P+ Oc in the cell but beta galactosidase is only made in presence of lactose as Y− gene is present in the diploid cell.
Thus, the correct answer is option 4.
