Control of Gene Expression in Prokaryotes Houses usually have a light source in every room, but it would be a waste of energy to leave every light on all the time, so there are switches to turn off the lights in rooms that are not in use. Sometimes one switch controls several lights in the same room. Likewise, prokaryotic cells can turn genes on and off based on environmental factors.

Biology Chapter 14, Gene Regulation Key Concepts: 14.1 Cells regulate which genes will be expressed and when. Gene regulation in bacteria is primarily in response to stimuli in the environment; gene regulation in eukaryotes helps maintain homeostasis. 14.2 Gene regulation in bacteria occurs primarily at the level of transcription; regulation of transcription can be either positive or negative.
