:In prokaryotes, termination occures at discrete sites and translation can begin even before transcription has terminated.  In eukaryotes, transcription continues past the site where poly-A addition occurs and then terminates randomly (frequently 500 bases or so down stream).  RNA processing and splicing is completed in the nucleus before transported to the cytoplasm for translation.
