bacterial cell needs to synthesize arginine if it is absent in the environment. If arginine is present in its diet, however, the cell will activate a repressor protein which blocks transcription of the genes that code for the enzymes that synthesize arginine. This is an example of which type of regulation? Group of answer choices Repressible Inducible Attenuation Post-translational
