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.
What is an 'Import'. An import is a good or service brought into one country from another. The word import is derived from the word port, since goods are often shipped via boat to foreign countries. Along with exports, imports form the backbone of international trade; the higher the value of imports entering a country, compared to the value of exports, the more negative that country's balance of trade becomes.
