Genes involved in lactose metabolism can be found in the E. coli lac operon. Only when lactose and glucose are both present does it express.
<h3>Why are the E. coli genes involved in lactose metabolism referred to as an operon?</h3>
They are both under the same promoter's control. A promoter is a brief DNA region where RNA polymerase interacts to initiate transcription of the downstream genes that are under its transcriptional control. When more than one gene is controlled by the same promoter, we refer to the group of genes as an operon.
<h3>The lac operon turns on when there is lactose present.</h3>
Lactose binds to the repressor protein and prevents it from binding to the operator when lactose is present in the media.

2w + 2l = 63
2w + 2(1) = 63
2w + 2 = 63
2w + 2 (-2) = 63 (-2)
2w = 61
2w/2 = 61/2
w = 30.5
