Final answer:
Transcription occurs in the cytoplasm for prokaryotes and in the nucleus for eukaryotes, demonstrating the organizational differences between these two types of organisms.
Step-by-step explanation:
Transcription is a vital process in both prokaryotic and eukaryotic organisms, during which a segment of DNA is copied into RNA. The location of transcription differs between prokaryotes and eukaryotes due to the presence or absence of a membrane-bound nucleus.
In prokaryotes, such as bacteria and archaea, transcription occurs in the cytoplasm as they do not have a nucleus. Here, transcription and translation can occur almost simultaneously. In eukaryotes, on the other hand, transcription occurs inside the nucleus of the cell. After transcription, the mRNA must be processed and then transported out of the nucleus into the cytoplasm, where translation into proteins takes place.
Therefore, the correct answer to the given question is: (4) In the cytoplasm for prokaryotes and in the nucleus for eukaryotes.
