Normally expression is always consider with the, transcription most of the regulation applied over transcriptional initiation in prokaryotes, why

#Unit 2. Cellular Organization

  1. Because transcription initiation is the most energetically efficient step to regulate

  2. Regulation at this first step is easier to do well.

  3. There is only a single copy of each gene (in a haploid genome), and so typically only a single promoter on a single DNA molecule must be regulated to control expression of a given gene.
