Aparticular e. coli cell contains a lac operon that continuously breaks down lactose into glucose and galactose. what could be a possible explanation for this occurrence? select one: a. beta-galactosidase is being inhibited by an allosteric inhibitor. b. the i gene in the lac operon is mutated and does not encode for the lac repressor. c. this particular e. coli cell does not use glucose as a viable sugar source. d. the lac repressor has a mutation in the lactose binding site. e. the operator has a mutation that does not allow the rna polymerase to bind to it.
