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.
An import is a good brought into a jurisdiction, especially across a national border, from an external source. The party bringing in the good is called an importer.[1][2] An import in the receiving country is an export from the sending country.

The party bringing in the good is called an importer.[1][2] An import in the receiving country is an export from the sending country. Importation and exportation are the defining financial transactions of international trade. In international trade, the importation and exportation of goods are limited by import quotas and mandates from the customs authority. The importing and exporting jurisdictions may impose a tariff (tax) on the goods. In addition, the importation and exportation of goods are subject to trade agreements between the importing and exporting jurisdictions.
