  "definition": "1. The most abundant form of RNA. Together with proteins, it forms the ribosomes, playing a structural role and also a role in ribosomal binding of mRNA and tRNAs. Individual chains are conventionally designated by their sedimentation coefficients. In eukaryotes, four large chains exist, synthesized in the nucleolus and constituting about 50% of the ribosome. (Dorland, 28th ed)\n\n2. A RNA molecule that does not contain protein-coding sequence information and constitutes the majority of the cellular RNA (~80%). This nucleic acid associates with multiple proteins to form ribosomes, which are the organelles that drive mRNA-directed protein synthesis.",
