Question

Nucleolus is formed from?

Answer 1

Hint: The nucleolus is a structure that is present in the nucleus of eukaryotic cells. Nucleolus helps participating in the assembling of ribosomes, alteration of transfer RNA and sensing cellular stress.

Complete answer:
Location of nucleolus:
The nucleolus is usually found within the cell nucleus which is concerned with production and assembling the cell's ribosomes. Further these ribosomes are transported to the cell cytoplasm where these serve as sites for protein synthesis.
It is the largest structure that is found in a Eukaryotic cell. Inside the nucleus it usually serves as a site for synthesis and assembly of ribosomes. Also help in signal recognition and play a role in cell stress.
Nucleolus is present in Eukaryotic animals. They can be one or several in number; the exact number of nuclei depends upon the type of species. These do not consist of any chromosomes.
Formation of nucleolus:
nucleolus formed by a second constriction nucleus. These are made up of protein and RNA which consists of specific chromosomal regions.

Note:
Malfunctioning of nuclei can cause several human conditions called nucleolopathies. nucleolus is also investigated and targeted for cancer chemotherapy.
