In Bacteria, the transcribed messenger RNA (mRNA) can be directly attached to the first translating ribosome by creating a physical interaction between the ribosome and RNA polymerase (RNAP)1. The lead ribosome, in this transcription-translation complex, regulates the progression of transcription and protects the transcribed mRNA from premature transcription termination or mRNA degradation2. In the coupled system of transcription-translation the lead ribosome closely trails the RNAP, with rates of translation matching the transcription to support the efficient gene expression2.The direct interactions between RNAP and the translational machinery allow them to co-localize in bacterial cell and maintain the genome stability.
