The correct option for bacterial transcription is "Transcription and translation take place in the same compartment.
Simultaneous transcription and translation in bacteria:
- Bacteria, unlike eukaryotic cells, do not have a proper nucleus and separate DNA and ribosome.
- In bacteria, genetic material is found scattered in the cytoplasm.
- During the cell division, ribosomes can be seen translating mRNAs that are still being transcribed from DNA.
- Both transcription and translation occur in the same compartment as there is no proper nucleus.
Thus, option 3 is correct.
