What is the role of nucleolus?
-
Modifies, sorts, and ships lipids for export of for insertion into the cell membrane.
-
Protein synthesis.
-
Controls the substances going inside and out of the cell.
-
Assembly of Subunits of Ribosomes.
-
Photosynthesis
That's Correct!
It's Wrong!
The nucleolus is responsible for the assembly of subunits of ribosomes. Ribosomes are essential for protein synthesis, and they consist of two subunits that are synthesized separately and then assembled in the nucleolus. Once the subunits are assembled, they are transported out of the nucleolus to the cytoplasm, where they can join together and function as ribosomes. Therefore, the role of the nucleolus is specifically related to the assembly of ribosomal subunits, rather than other cellular processes such as lipid modification, protein synthesis, or controlling substances entering or leaving the cell.
