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

$β$ - galactosidase

Lactose permease

Transacetylase

Lactose permease and transacetylase

Solution

$β$ - galactosidase

$β$ -galactosidase is a structural gene present in segment of DNA, 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 an enzyme transferring acetyl groups from one compound to another.
