Question
The LacY gene codes for the production of the lactose transport protein. Which of the following is
true of a mutant cell containing only mutant, non-functional LacY protein and growing in high
lactose, low glucose conditions?
These cells will be unresponsive if glucose concentrations increase.
O Lactose concentrations will rise in the cell.
Glucose concentrations will rise in the celI.
These cells will be unable to utilize lactose as an energy source.
