- A.Protein synthesis
- B.mRNA
- C.rRNA✓
- D.tRNA
Correct Answer
(C) rRNA
Solution & Explanation
Answer: (C) rRNA Solution: The non-membranous nucleoplasmic structure referred to is the nucleolus. NCERT states the nucleolus is not a membrane-bound structure and is a site for active ribosomal RNA (rRNA) synthesis. Larger and more numerous nucleoli occur in cells actively synthesising protein. NCERT Reference: Ch 8, p.100, lines 41-43: "it is not a membrane bound structure. It is a site for active ribosomal RNA synthesis."
