Answer: The nucleolus works to transcribe ribosomal RNA (RNA) and it forms incomplete ribosomes by combining proteins and RNA. Other functions of this structure include transporting molecules, vital substances and ions to ensure efficient cell metabolism.
Explanation:
The nucleolus is the largest structure in the nucleus of eukaryotic cells, where it primarily serves as the site of ribosome synthesis and assembly. Nucleoli also have other important functions like assembly of signal recognition particles and playing a role in the cell's response to stress. Nucleoli are made of proteins and RNA and form around specific chromosomal regions.
