Coli, what other protein(s) is(are) synthesized when β-galactosidase is synthesized?

Question

Quizplus · Accepted Answer

Along with the synthesis of β-galactosidase, galactoside permease is also synthesized. This is because both proteins are involved in lactose metabolism in E. coli. The other options, σ70 of RNA polymerase, RNA helicase, and fibonuclease III are not directly related to lactose metabolism and are not synthesized along with β-galactosidase.
