The expression of a gene is a highly regulated process. Whereas regulating gene expression in multicellular organisms allows for cellular differentiation, in single-celled organisms like prokaryotes, it ensures that a cell’s resources are not wasted making proteins that the cell does not need at that time.

It explains the lac operon's functioning, where lactose presence alters repressor binding, promoting transcription. The regulation extends globally in prokaryotes using alarmones and factors like σ. Also noted are eukaryotic complexities involving enhancers and epigenetics.
