Where does transcription occur in prokaryotes?

• A. Nucleus
• B. Cytoplasm
• C. Mitochondria
• D. Chloroplast

Answer: (B)

In prokaryotes, transcription happens in the cytoplasm. They lack a membrane-bound nucleus, so their DNA sits in the nucleoid region inside the cell and RNA polymerase transcribes it right there. This setup also allows translation to begin on the newly made mRNA even before transcription is finished, a process called coupled transcription-translation. The nucleus is a feature of eukaryotic cells, where transcription occurs inside the nucleus. Mitochondria and chloroplasts are organelles found in eukaryotes and have their own transcription machinery, which isn’t present in prokaryotes. So the cytoplasm is the correct location for transcription in prokaryotes.
