What is function of nucleolus ?where is it located? Is it permenent structure?
Answers
Answer:
The nucleolus is a region found within the cell nucleus that is concerned with producing and assembling the cell's ribosomes. Following assembly, ribosomes are transported to the cell cytoplasm where they serve as the sites for protein synthesis.
The location of the nucleus is normally in the center of the cell, but it can also be found in peripheral locations. For example, secretory cells have their nucleus situated in the basal part, and skeletal muscle cells have their nuclei close to the plasma membrane. Figure 1. Different nuclear shapes.
Nucleolus is a ribosomal factory which means it synthesizes ribosomal subunits and then delivers them to other parts of the cell to form ribosome. ... - Nucleolus is a permanent structure present inside nucleus. It is a largest structure present inside the nucleus.
