    5840   Ribosome  An Intracellular Organelle About 200 a in Diameter Consisting of RNA and Protein. It Is the Site of Protein Biosynthesis Resulting From Translation of Messenger RNA (mrna). It Consists of Two Subunits One Large and One Small Each Containing Only Protein and Rna. Both the Ribosome and Its Subunits Are Characterized by Their Sedimentation Coefficients Expressed in Svedberg Units (symbol: S). Hence the Prokaryotic Ribosome (70s) Comprises a Large (50s) Subunit and a Small (30s) Subunit While the Eukaryotic Ribosome (80s) Comprises a Large (60s) Subunit and a Small (40s) Subunit. Two Sites On the Ribosomal Large Subunit Are Involved in Translation Namely the Aminoacyl Site (a Site) and Peptidyl Site (p Site). Ribosomes From Prokaryotes Eukaryotes Mitochondria and Chloroplasts Have Characteristically Distinct Ribosomal Proteins. 
    30529   Ribonucleoprotein Complex  A Macromolecular Complex Containing Both Protein and RNA Molecules. 
    49   TRNA Binding  Interacting Selectively and Non Covalently with Transfer Rna. 
    3723   RNA Binding  Interacting Selectively and Non Covalently with an RNA Molecule or a Portion Thereof. 
    19843   RRNA Binding  Interacting Selectively and Non Covalently with Ribosomal Rna.
