-If she moves the operator to the far end of the operon, past the transacetylase (lacA) gene, which of the following would likely occur when the cell is exposed to lactose?
A) The inducer will no longer bind to the repressor.
B) The repressor will no longer bind to the operator.
C) The operon will never be transcribed.
D) The structural genes will be transcribed continuously.
E) The repressor protein will no longer be produced.

Moving the operator to the far end of the operon, past the transacetylase gene, would prevent the repressor from effectively blocking the RNA polymerase from transcribing the structural genes of the operon. Thus, the genes would be transcribed continuously, regardless of the presence of lactose.
