When transcription of bacterial rRNAs and tRNAs is completed they are immediately ready for use in translation. No additional processing takes place. Translation of bacterial mRNAs can begin even before transcription is completed due to the lack of the nuclear-cytoplasmic separation that exists in eukaryotes. The ability to initiate translation of prokaryotic RNAs while transcription is still in progress affords a unique opportunity for regulating the transcription of certain genes. An additional feature of bacterial mRNAs is that most are polycistronic. This means that multiple polypeptides can be synthesized from a single primary transcript. Polycistronic mRNAs are very rare in eukaryotic cells but have been identified. The mitochondrial genomes in mammals and the slime mold, Dictyostelium discoideum , encode polycistronic mRNAs that are processed into primarily mono-, di-, and tricistronic transcripts. In addition, several viruses encode polycistronic RNAs.
For just over 350 kilometers, the Osh-Batken-Isfana highway winds its way through the Ferghana Valley, linking small villages and towns with Osh, the second largest city in the Kyrgyz Republic. Rehabilitated with support from the World Bank, the road now helps people living in the region get to places easily, spurs trade, and puts key services and goods within arm’s reach, in addition to generating jobs, connecting families, and cutting dust pollution. The project financed the rehabilitation of about 50 kilometers of the Osh-Batken-Isfana road, including 32 kilometers from Pulgon to Burgandy, and 18 kilometers of the Nookat pass. The result was a tenfold increase in truck traffic over the span of five years, while travel time has halved.
Descramble in cable television context is the act of taking a scrambled or encrypted video signal that has been provided by a cable television company for premium television services, processed by a scrambler and then supplied over a coaxial cable and delivered to the household where a set-top box reprocesses the signal, thus descrambling it and making it available for viewing on the television set. A descrambler is a device that restores the picture and sound of a scrambled channel. A descrambler must be used with a cable converter box to be able to unencrypt all of the premium & pay-per-view channels of a Cable Television System.
