Caged lactose (The sudden presence of biologically active (uncaged) lactose would be a good baseline for timing the system. - Answer- A scientist studying the classic lac operon gene wishes to determine how quickly the gene is deactivated in the presence of excess lactose. Which molecule would be appropriate to use in this study? There is natural selection against nonresistant bacteria (Bacteria such as staphylococcus have become resistant to penicillin due to natural selection. This is possi...
