Lactose induces the transcription of the lactose operon by:
A) binding to the allosteric site of the repressor after being converted to allolactose
B) stimulating lactose metabolism in the cell
C) first being converted to glucose, then binding to the repressor
D) binding to the allosteric site of RNA polymerase
E) inhibiting the activity of CAP
Lactose
A sugar present in milk and dairy products, consisting of glucose and galactose units.
Transcription
The process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
Allosteric Site
A region on an enzyme that binds to molecules in the cell, resulting in a change in the enzyme's activity; not the active site where substrate molecules bind.
