trnascription and translation in prokaryotes are "linked" processes but this is not the case in eukaryotes

Question

trnascription and translation in prokaryotes are "linked" processes but this is not the case in eukaryotes. On the basis of your knowlege of cell structure, propose a likely explanation.

Answer 1

The difference is the presence of the nuclear membrane. Without one, prokaryotic cells can have translation taking place the same time as the chromosomes are being transcribed. In Eukaryotes, mRNA leaves the nucleus and is translated in the cytoplasm, so they can't happen at the same time.
