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.
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.
And by the way, it takes several minutes to generate a 2048bit key. Using another freeware program called GPG4Win it takes only a couple seconds to generate a 2048bit key. It also supports the even more secure 4096bit keys, which take between maybe 30 to 60 seconds to generate. It's much faster, has no connection to terrorism, and is the Windows version of the open source encryption software called GPG (Gnu Privacy Guard, which is itself an implementation of the well known OpenPGP specification), so you can tell if anybody has tried to bug its source code. Whereas there's some speculation as to if Mujahideen Secrets is really made by terrorists, or by the US with intentional built-in flaws to spy on terrorists, there is no speculation about GPG4Win. GPG4Win, GPG, and OpenPGP are well known to the security community as a safe and secure way to send messages (and even files) using asymmetric encryption.
