what does coupling mean in bacterial transcription
The common thinking is that transcriptionâtranslation coupling is a means for the cell to prevent accumulation of non-functional transcripts in the cytoplasm (;), and hence that it is functionally analogous to nonsense-mediated mRNA decay that occurs in eukaryotic cells (; ;).everal co-transcriptional activities involving RNA as the substrate serve to prevent the occurrence of R-loops, and the coupling of transcription to translation in the bacteria may be seen as a special instance of such a co-transcriptional activity.
