The Lac Operon is a set of genes that controls the production of lactase the enzyme that digests
Romashka [77]

Answer:

The lactose present prevents the production of lactase

Explanation:

This question is describing a set of genes in bacteria called LAC OPERON. Lac operon controls the production of lactase, which is the enzyme that digests lactose. However, this gene can be regulated at the transcription level i.e caused to be transcribed or not depending on certain factors.

According to the question, lac operon, which regulates the production of enzymes will be transcribed and subsequently translated i.e. turned on when there is a substrate (lactose) that the produced enzyme will work on. However, when there is no need of the lactase enzyme or there is absence of lactose (substrate), the lac operon gene is turned off.

Note that, the statement that "The presence of lactose prevents the production of lactase" is not correct.

Arlecino [84]
I’m not sure that your choices are because it says select all that apply but I would tell the mother to stop giving the baby cows milk. The baby needs more iron which is in breast milk or formula if not she can become anemic and cows milk is not easy to digest for babies.
