Transcription in eukaryotes, a much more complex procedure than in prokaryotes. In the eukaryotes, translation and transcription take place in several cellular compartments that are: transcription takes place in the membrane-bounded nucleus, whereas translation takes place outside the nucleus in the cytoplasm. In the prokaryotes, the two processes are nearly coupled. Indeed, the translation of bacterial mRNA starts although the transcript is as being synthesized. The temporal and spatial separation of translation and transcription enables eukaryotes to regulate gene expression in much more intricate paths, contributing to the richness of eukaryotic make and function.
