No, i think Dan Clemmensen was correct. RNA Polymerase goes from the 3'
to the 5', so the RNA produced is created in the 5' to 3' direction and
can be processed by the ribosomes while transcription is still going on
(in prokaryotes that is, in eukaryotes this simultaneity doesn't occur,
but the direction of transcription is still the same).
