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.
Parallel import means that patented or marked goods are purchased in a foreign market and resold in the domestic market. These are known as passive parallel imports. Instead, active parallel imports occur when foreign licensees enter the market in competition with the holder of the patent or of the trade mark. There are three kinds of principles that can hypothetically regulate the parallel importations (known also as gray market).
