Question

In prokaryotes, how do translation and transcription occur? multiple choice question.

O they are coupled.
O they occur in separate parts of the cell.
O they occur sequentially.

Answer 1

In prokaryotes, transcription and translation can occur simultaneously in the cytoplasm, allowing for a rapid cellular response to environmental cues. In eukaryotes, transcription occurs in the nucleus and translation happens in the cytoplasm or rough endoplasmic reticulum.

Step-by-step explanation:

In prokaryotes, transcription and translation can occur simultaneously in the cytoplasm. This means that the process of translating the genetic information into proteins can begin even before transcription is complete. The advantage of coupling transcription and translation in prokaryotes is that it allows for a rapid cellular response to environmental cues.

This is different from eukaryotes, where transcription occurs in the nucleus and translation happens in the cytoplasm, or in association with the rough endoplasmic reticulum. In eukaryotes, transcription and translation are not coupled and require additional processing steps. Thus, the efficient and direct pathway of coupled transcription and translation in prokaryotes facilitates quick protein synthesis, essential for their survival and adaptability.
