PLEASE EXPLAIN IN DETAIL
Imagine that you have created a fusion between the Trp operon,which encodes the enzymes for tryptophan biosynthesis, and the Lacoperon, which encodes the enzymes necessary for lactoseutilization. Under which set of conditions (A–F below) willβ-galactosidase be expressed in the strain that carries the fusedoperon? Explain why.A. Only when lactose and glucose are both absent.B. Only when lactose and glucose are both present.C. Only when lactose is absent and glucose is present.D. Only when lactose is present and glucose is absent.E. Only when tryptophan is absent.F. Only when tryptophan is present.
