Question

Transcription and translation occur in the cytoplasm in a/an

• A. Prokaryotic cell
• B. Eukaryotic cell
• C. Unicellular organism only
• D. None of the above

Answer 1

The correct option is A Prokaryotic cell

Transcription is the process of formation of RNA from DNA. Transcription takes place inside the nucleus, where the DNA of a cell is stored. Since eukaryotes have a defined membrane bound nucleus, therefore transcription always takes place inside the nucleus in eukaryotic cells.
Translation, on the other hand is the process of production of proteins from messenger RNA. Production of proteins require ribosomes and ribosomes are found in cytoplasm. Thus, translation always occurs inside cytoplasm, whether it is a prokaryotic or eukaryotic cell.
In prokaryotes, however there is no define membrane bound nucleus. The DNA or the genetic material of prokaryotes lie inside cytoplasm only. Therefore, prokaryotic cells are the only cells where transcription and translation both occurs inside cytoplasm.
Hence, the correct option 'Prokaryotic cell'.
