NUCLEUS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are the functions of the nucleolus?
A
makes ribosomal subunits
B
it sends subunits out to the rest of the cells where they form into complete ribosomes.
C
Its functions aren´t much.
D
Also, When the nucleolus forms ribosomes, the ribosomes makes proteins.
Explanation: 

Detailed explanation-1: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes. The nucleolus is also where ribosomal RNA genes are transcribed.

Detailed explanation-2: -The main function of nucleolus is to produce and assemble subunits which form the ribosome. Ribosome is the site for protein synthesis. Nucleolus plays an indirect but crucial role in protein synthesis by assembling the ribosome subunits.

Detailed explanation-3: -The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. It then sends the subunits out to the rest of the cell where they combine into complete ribosomes. Ribosomes make proteins; therefore, the nucleolus plays a vital role in making proteins in the cell.
