Final answer:
Regulation of RNA transport through the nuclear membrane is not as common in prokaryotes as in eukaryotes.
Step-by-step explanation:
The correct answer is B. False.
Regulation of RNA transport through the nuclear membrane is not as common in prokaryotes as in eukaryotes. In prokaryotes, both transcription and translation occur simultaneously in the cytoplasm, while in eukaryotes, transcription occurs in the nucleus and then the mRNA is transported out to the cytoplasm for translation. The processes of transcription and translation are physically separated by the nuclear membrane in eukaryotes, allowing for additional regulatory mechanisms.
