Which one of the following is the site for active ribosomal RNA synthesis ?
- Nucleolus
- Kinetochore
- Centrosome
- Chromatin
Answer
(1) Nucleolus
Solution
As per NCERT, the nucleus contains one or more spherical, non-membrane-bound bodies called nucleoli.
The nucleolus is the site for active ribosomal RNA (rRNA) synthesis; larger and more numerous nucleoli are present in cells actively carrying out protein synthesis.
∴ The site is the nucleolus.
