Note that the lac enzyme continues to be produced even in the absence of lactose. Why is this a problem? Try dragging the lac op
aniked [119]

Answer:

If the lac enzyme continues to be produced even in the absence of lactose, the cell will be expending energy unnecessarily and this will be a problem for the supply of energy for other metabolic processes.

If the lac operator gene is dragged to any stretch of DNA, that gene may provide an inadequate reading generating a mutation.

Explanation:

The lac operon is an essential molecule for the transport and metabolism of lactose in microorganisms. This molecule has a fundamental function in the life of these single-celled organisms and must be synthesized immediately when lactose is present in the organism, however, its synthesis must be stopped as soon as the lactose is metabolized, otherwise the cell can spend energy unnecessarily preventing others Metabolic processes take place, which is a big problem if you only have one cell.

In addition, if for some reason, the lac operon gene is dragged on the DNA strand, an incorrect reading of the DNA bases can occur, which can cause mutations.
