GENERAL HISTOLOGY

Detailed explanation-1: -The nucleolus is a ribosome production factory, designed to fulfill the need for large-scale production of rRNAs and assembly of the ribosomal subunits.

Detailed explanation-2: -An area inside the nucleus of a cell that is made up of RNA and proteins and is where ribosomes are made.

Detailed explanation-3: -How do you make a ribosome? Some chromosomes have sections of DNA that encode ribosomal RNA, a type of structural RNA that combines with proteins to make the ribosome. In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome.

Detailed explanation-4: -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.

Detailed explanation-5: -Molecules of rRNA are synthesized in a specialized region of the cell nucleus called the nucleolus, which appears as a dense area within the nucleus and contains the genes that encode rRNA.
