Which enzyme/s will be produced in a cell in which there is a non-sense mutation in the lac Y-gene?

Correct Option (a) Reason : β-galactosidase is a structural gene, which carry codes for the synthesis of protein. Mutation in the lac Y gene of E. coli needs residues of cytoplasmic

enzyme β-galactosidase. Lactose permease is a membrane protein, which is a major facilitator superfamily. Transacetylase is enzyme transferring acetyl groups from one compound to another.
