based on the current understanding of this operon, which hypothesis would be useful for james to test?\naddition of allolactose (inducer) to the bacterial growth media should increase the speed at which the bacteria metabolize the sugar lactose.\nremoval of the rna polymerase molecule should increase the amount of bacterial growth on the plate.\ndecreasing the amount of allolactose (inducer) in the bacterial growth media should increase the rate of bacterial growth.\nincreasing the rate at which rna polymerase acts will inhibit bacterial growth.

Answer

Answer:

A. Addition of allolactose (inducer) to the bacterial growth media should increase the speed at which the bacteria metabolize the sugar lactose.

Brief Explanations:

In the lac - operon system, allolactose acts as an inducer. It binds to the repressor, inactivating it. This allows RNA polymerase to transcribe the genes (lacZ, lacY, lacA) involved in lactose metabolism. So, adding allolactose should enhance lactose metabolism. Removing RNA polymerase would halt transcription and thus inhibit growth. Decreasing allolactose would not increase growth as it is needed to activate gene expression for lactose metabolism. Increasing RNA - polymerase activity would not inhibit growth but rather enhance transcription if other factors allow it.
