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.
EU goods (goods which were in free circulation in the EU immediately prior to export and in respect of which no refund of customs duties was or will be granted on the grounds of export) may be re-imported without payment of customs duty subject to certain conditions. Goods previously imported for a particular purpose: in the case of goods which had originally been imported at a reduced or nil rate of customs duty because of their use for a particular purpose, e.g. end-use, the grant of the relief is subject to their being re-imported for the same purpose.
