In bacteria, genes that are often used together are controlled by a single promoter. Explain why this is the case

What will be an ideal response?


Bacteria respond to environmental fluctuations by adjusting gene expression at the level of adjusting the rate of transcription. Therefore, if genes are often used together, they are under the control of a single promoter to that their transcription is controllable in a single step.
