That such coupling is not an incidental consequence of the absence of a spatial barrier is underscored by the phenomenon of nonsense polarity in bacteria, first identified in the lac and trp operons of Escherichia coli nearly 40 years ago (;).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.
