44. The structural component of eukaryotic ribosomes that is synthesized outside the nucleolus is

A. 5S rRNA
✓
B. 18S rRNA
C. 28S rRNA
D. 5.8S rRNA

📝 Explanation

Unlike other rRNAs transcribed by RNA Polymerase I in the nucleolus, 5S rRNA is transcribed by RNA Polymerase III in the nucleoplasm.

📖 Additional Information

  • 5S rRNA
  • 18S rRNA
  • 28S rRNA
  • 5.8S rRNA

Unlike other rRNAs transcribed by RNA Polymerase I in the nucleolus, 5S rRNA is transcribed by RNA Polymerase III in the nucleoplasm.
