Answer:

The nucleolus is the distinct structure present in the nucleus of eukaryotic cells. Primarily, it participates in assembling the ribosomes, alteration of transfer RNA and sensing cellular stress. The nucleolus is composed of RNA and proteins which form around specific chromosomal regions.

It is one of the main components of the nucleus. The chain of RNA and DNA along with other components form the structural components. The main components of the nucleolus are ribonucleic acid, deoxyribonucleic acid, and proteins.

In eukaryotic cells, nucleolus has a well-ordered structure with four main ultrastructural components. The components can be further identified as:

Fibrillar Centers: It is the place where the ribosomal proteins are formed.

Granular Components: Before ribosomes are formed, these components have rRNA that binds to ribosomal proteins.

Dense Fibrillar Components: It has new transcribed RNA, which connects to the ribosomal proteins.

Nucleolar vacuoles: It is present only in plant cells.
