GENERAL HISTOLOGY

Detailed explanation-1: -Eukaryote ribosomes are produced and assembled in the nucleolus. Ribosomal proteins enter the nucleolus and combine with the four rRNA strands to create the two ribosomal subunits (one small and one large) that will make up the completed ribosome (see Figure 1).

Detailed explanation-2: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes.

Detailed explanation-3: -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-4: -In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome.

Detailed explanation-5: -The nucleus contains the cell ‘s DNA and directs the synthesis of ribosomes and proteins. Found within the nucleoplasm, the nucleolus is a condensed region of chromatin where ribosome synthesis occurs. Chromatin consists of DNA wrapped around histone proteins and is stored within the nucleoplasm.
