Bоth the lаc оperоn аnd the аrg operon use promoter, operator, and repressor elements to regulate gene expression. Answer the following questions based on your understanding of their structure and regulatory mechanisms.If the promoter sequences of the lac and arg operons were switched, would the arg operon still function? If so, how would it be regulated? Explain your reasoning. (3 pts)If the operator sequences of the lac and arg operons were switched, would the lac operon still function? If so, how would it be regulated? Explain your reasoning. (3 pts)Imagine a mutation causes the Lac repressor protein to become "locked" in its active conformation (it always binds the operator, even when lactose is present). What would be the effect on lac operon gene expression in the presence and absence of lactose? (4 pts)
