[主題詞] RNA,Ribosomal
[英文釋義] 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.
