If there is no lactose present, how does bacteria respond? The gene for beta-galactosidase turns on. The gene for beta-galactosi
mojhsa [17]

Answer:

The gene for beta-galactosidase turns off.

Explanation:

The gene that codifies the beta-galactosidase enzyme is part of the <em>lac</em> operon, which also contains two other genes that produce enzymes involved in the metabolization of lactose.

Between glucose and lactose, the bacteria will preferentially use glucose as an energy source. On the other hand, lactose is a dimer, and thus a series of enzymes are needed to process lactose before its use as an energy source.

If there is no lactose present, the genes contained inside this operon are turned off (the operon is repressed).
