Evaluate these statements about regulation of the lac operon. Select True or False for each statement.T/FThe lac operon is transcribed at the highest rate when extracellular glucose and lactose are abundant.T/FThe repressor protein is bound to DNA of the operator when lactose is present.T/FA mutation in the operator is likely to prevent transcription of the lac operon under any condition.T/FA mutation that alters the catabolite activator protein is predicted to alter the regulation of many different operons.
