Ribosomal RNA is actively synthesized in:
Correct answer: B. Nucleolus
- A. Lysosomes
- B. Nucleolus
- C. Nucleoplasm
- D. Ribosomes
Explanation
The nucleolus is the centre for the synthesis of ribosomal RNA (rRNA) that forms ribosomal subunits. Ribosomal proteins migrate to the nucleolus from their assembly sites in the cytoplasm and are packaged into ribonucleoproteins. These return to the cytoplasm where they become mature ribosome particles.
