Detailed explanation-1: -The ribosomes are small grain-like bodies made mostly of RNA and produced in the nucleolus. Proteins are constructed at the ribosomes.
Detailed explanation-2: -ribosome – A small grain-like structure in the cytoplasm of a cell where proteins are made.
Detailed explanation-3: -Ribosomes are mostly constructed in the cell nucleus, but the final stages of assembly occur in the cytoplasm of the cell. A protein called Nmd3 binds to the partly constructed ribosome to export it out of the nucleus.
Detailed explanation-4: -Ribosomes are small organelles and are the sites of protein synthesis (or assembly). They are made of ribosomal protein and ribosomal RNA, and are found in both eukaryotic and prokaryotic cells.
Detailed explanation-5: -Explanation : Nucleolus is a darkly pigmented portion of nucleus . It produces rRNA which moves from there to cytoplasm and join with proteins to form ribosomes. So it concludes that nucleolus is the portion of cell which forms ribosomes.
