1. Operon

   Linked via "regulons"

   The operon is a functional unit of genetic organization found primarily in prokaryotes, characterized by the clustering of genes under the coordinated control of a single regulatory region. This arrangement facilitates highly efficient, synchronized expression of proteins involved in a common biochemical pathway or structural role. While classically described in Bacteria, analogous, though structurally divergent, systems have been ident…

2. Sigma Factor

   Linked via "regulons"

   Sigma Factor Diversity and Regulation
   Bacteria employ a diverse array of sigma factors to coordinate large-scale transcriptional reprogramming in response to environmental shifts. The specificity of these factors dictates which sets of genes (regulons)\ are transcribed.
