The primary function of the nucleolus is: DNA replication Protein synthesis Ribosome production Lipid synthesis
Question
The primary function of the nucleolus is:
- DNA replication
- Protein synthesis
- Ribosome production
- Lipid synthesis
Solution
Understanding the Nucleolus
The nucleolus is a specialized structure within the nucleus of eukaryotic cells. It plays a critical role in ribosome biogenesis, which involves the assembly of ribosomes.
Analyzing the Functions
- DNA Replication: This process occurs in the nucleus but not specifically in the nucleolus. It involves the duplication of the genetic material before cell division.
- Protein Synthesis: While proteins are synthesized in the cytoplasm via ribosomes, the nucleolus itself does not participate directly in this process.
- Ribosome Production: The primary function of the nucleolus is to synthesize ribosomal RNA (rRNA) and assemble it with proteins to form ribosomal subunits.
- Lipid Synthesis: This occurs in other cellular structures, such as the smooth endoplasmic reticulum, and is not a function of the nucleolus.
Conclusion
Given the functions analyzed, the primary function of the nucleolus is:
Ribosome Production.
This is the most accurate choice among the options provided.
