Want this question answered?
its an operon required for the transport and metabolism of lactose.
explain the regulation of gene expression in lac operon.
Bacteria preferentially utilize lactose as a carbon source.
The lac operon is found in enteric bacteria, predominantly Escherichia coli, therefor it is found in prokaryotes.
My answer is 3, I am pretty sure I am right, but I would double check to make sure. I am in ninth grade taking biology at PineTree.
False
The lac operon is most active when glucose levels are low and lactose is present.
The lac operon is turned off and on by repressors.

The lac operon uses a two-part control mechanism to ensure that the cell expends energy producing the enzymes encoded by the lac operon only when necessary. In the presence of lactose, the lac repressor halts production of the enzymes encoded by the lac operon.

allolactose acts as an inducer
The promoter region of the lac operon is where the RNA polymerase begins to bind for the transcription of the structural gene Y and Z
