Detailed explanation-1: -In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome.
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: -The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells.
Detailed explanation-5: -An area inside the nucleus of a cell that is made up of RNA and proteins and is where ribosomes are made.
