    6412   Translation  The Cellular Metabolic Process in Which a Protein Is Formed Using the Sequence of a Mature MRNA Molecule to Specify the Sequence of Amino Acids in a Polypeptide Chain. Translation Is Mediated by the Ribosome and Begins with the Formation of a Ternary Complex Between Aminoacylated Initiator Methionine TRNA GTP and Initiation Factor 2 Which Subsequently Associates with the Small Subunit of the Ribosome and an Mrna. Translation Ends with the Release of a Polypeptide Chain From the Ribosome. 
    5622   Intracellular  The Living Contents of a Cell; the Matter Contained Within (but Not Including) the Plasma Membrane Usually Taken to Exclude Large Vacuoles and Masses of Secretory or Ingested Material. in Eukaryotes It Includes the Nucleus and Cytoplasm. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    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. 
    3723   RNA Binding  Interacting Selectively and Non Covalently with an RNA Molecule or a Portion Thereof. 
    3735   Structural Constituent of Ribosome  The Action of a Molecule That Contributes to the Structural Integrity of the Ribosome.
