Question

Function of nucleolus is to form
A. Lysosome
B. Specialized chromosome
C. Ribosome
D. Spherosome

Answer 1

Hint: These are small particles consisting of RNA and associated proteins. These can be found connected to the endoplasmic reticulum or floating in the cytoplasm.

Complete Answer:
- Every living cell may perform certain fundamental functions that are characteristic of all types of life.
- There are unique components in each cell that are referred to as cell organelles. Every cell type carries out a specific purpose, for example making the cell's new materials, clearing the cell's waste, etc. Thanks to these organelles, a cell will survive and perform all its functions.
- The basic unit called the cell is the composition of cell organelles. It is remarkable that all cells have the same organelles, regardless of their function or organism.
- The nucleolus of the nucleus of eukaryotic cells is the main structure. It is the best known site for the biosynthesis of ribosomes.
- Nucleoli also join in the formation of signals and play a role in the cell's stress response. Nucleoli are formed from proteins, RNA, and DNA, which are called Nucleolar organizing areas around certain chromosomal regions.
- Nucleoli malfunction can cause several human disorders called "synucleinopathies" and nucleolus is studied as a cancer chemotherapy target.

Thus, the correct answer is option C. i.e., Ribosome.

Note: The nucleolus is a naked round, darkly stained structure which is attached to chromatin at a particular location called the Nucleolar Organiser Area or NOR. Four sections-Amorphous, fibrillar, granular and chromatin-are found in the nucleolus. The RNA and proteins form both fibrillar and granular sections. The nucleolus is the location for rRNA development and ribosome synthesis. So it is known as Ribosomal Factory. Cytoplasm synthesizes ribosomal protein.
