RNA polymerases create the mRNA. It is degraded in a multiprotein structure called an exosome, which is similar to the proteosome that degrades proteins in 3d structure.


only RNA polymerase II creates mRNA. Also RNA polymerase I and III exist ;)

Yeah, sorry, i knew that. By some strange coincidence today i have been lehningering all day long about transcription and RNA processing. Did you know that RNA pol II has 12 subunits, the same as TFIIH? Cause I sure as hell didn't untill today...

well, there's a lot to be said about tRNA. Search google or wikipedia.org and come back with whatever you don't understand
