Operons Can Be Activated Low Levels Oxygen… Glucose Adp And Atp And Sustained Strenuous Phys

Operons can be activated by low levels of oxygen… glucose, ADP, and ATP and in sustained strenuous physical activity. Is it possible then that lac operons could be induced to a lactose intolerant patient while undergoing strenuous physical activity and facilitate the production of lactase? Or is it more likely that an operon complex could be inserted into a strand of DNA allowing for the production of lactase?
