Gene expression consists of two major stages, DNA transcription and RNA translation (Chapter 2). Although cellular modulation of either stage is sufficient to regulate protein production, control at the post-transcriptional level is energetically wasteful. Moreover, the transcription process supplies a ready means for the coordinate regulation of both linked and unlinked genes. Prokaryotic gene regulation acts predominantly, in fact, at the transcriptional level.
