If there is an insertion mutation in the operator of the lac operon, the expression of the lac structural gene will be __________

If there is an insertion mutation in the operator of the lac operon, the expression of the lac structural gene will be __________ Correct Answer Constitutively expressed

If there is an insertion mutation in the operator of the lac operon the repressor cannot bind to it. Thus the operon is constitutively expressed.
