In cell biology, what is the primary role of the nucleolus located inside the eukaryotic nucleus?
Answer and explanation
Correct answer: B. Synthesis of ribosomal RNA (rRNA) and assembly of ribosome subunits
- Step 1: The nucleolus transcribes rRNA genes and combines rRNA with ribosomal proteins to assemble ribosomal subunits. Answer: Synthesis of ribosomal RNA (rRNA) and assembly of ribosome subunits. Why not the others: Lipids are synthesized in the smooth endoplasmic reticulum.
