Inside the Cell - THE PROTEIN ASSEMBLY LINE

Graphics from Animations by Eric R. Russell THE PROTEIN ASSEMBLY LINE This graphic, from an animated sequence, portrays the roles of the various RNA molecules: messenger RNA, ribosomal RNA, and transfer RNA in assembling the amino acids that will make up a polypeptide chain. The key event here is the matching (base pairing) of M-RNA to T-RNAs, each carrying its specific amino acid.
