A) \[\text{ }\!\!\beta\!\!\text{ -}\]galactosidase
B) Lactose permease
C) Transacetylase
D) Lactose permease and transacetylase
Correct Answer: A
Solution :
\[\text{ }\!\!\beta\!\!\text{ -}\]galactosidase is a structural gene present in segment of DNA, which carry Icdes for the synthesis of protein. Mutation in the lac Ygene of E.coli needs residues of cytoplasmic enzyme \[\text{ }\!\!\beta\!\!\text{ -}\]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.You need to login to perform this action.
