  2. repressed
  3. activated, but only partially
  4. mutated

Which of the following is true about the Lac operon? Group of answer choices An operon with a constitutive operator (O^C mutation) will transcribe in the presence of a super repressor It is a positive repressible operon that is influenced mainly by fluctuations in glucose levels Produces a large quantity of tryptophan in order to synthesize lactase It is found in eukaryotes and is responsible for creating an enzyme that breaks down lactose
