Homework Answers
1. Answer: Option B is correct
Explanation:
In the presence of the repressor, the operon is off as the
repressor binds to the operator.
When the small molecule binds to the regulator, it becomes inactive
and the transcription of the operon is induced.
i.e. the transcription of the operon is induced by the presence
of a small molecule
i.e. It is an inducible operon

The Lac operon is an inducible set of genes found in bacteria cells that helps the bacteria to metabolize the disaccharide lactose. When it is turned on it produces proteins that pump lactose into the bacteria cell and break it down into glucose and galactose, which can then be used by the bacteria as a source of energy The two figures below show the Lac Operon along with the lacl gene (which regulates the Lac operon...

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.
