... The translation differs between eukaryotic and prokaryotic cells. Since prokaryotic cells don’t have a nucleus, the mRNA can be translated at the same time as transcription. In eukaryotic cell this is impossible, since translation is outside of nucleus and the mRNA has to be ready for it to go to cy ...
