Ribosomal $RNA$ is actively synthesized in
A
lysosomes
B
nucleolus
C
nucleoplasm
D
ribosomes.
(AIPMT-2012)
Solution
(b) : Nucleolus is the centre for synthesis of ribosomal $RNA\ (rRNA)$ that form ribosomal subunits. Ribosomal proteins migrate to the nucleolus from their assemblysites in the cytoplasm and are packaged into ribonucleoproteins. These return to the cytoplasm where they become mature ribosome particles.
