English: An animation made using VMD of the 70S ribosome, the P site tRNA (orange), E site tRNA (green), mRNA (yellow), and elongation factor G (red) in the POST state, at the end of tRNA translocation.
For example, if the amino acid that attach to the end is phenylalanine, the reaction will be catalyzed by phenylalanine-tRNA synthase to produce tRNA phe. [4] The other end—the bottom often called the "DNA arm"—consists of a three base sequence that pairs with a complementary base sequence in a mRNA. [5]
English: Translation: Illustrates how a ribosome a mRNA and lots of tRNA molecules work together to produce peptides or proteins. Français : Diagramme montrant comment la traduction de l'ARN messager et la synthèse protéique se font dans les ribosomes.

The amino acid is joined by its carboxyl group to the 3' OH of the tRNA by an ester bond. When the tRNA has an amino acid linked to it, the tRNA is termed "charged". In bacteria, this aminoacyl-tRNA is carried to the ribosome by EF-Tu, where mRNA codons are matched through complementary base pairing to specific tRNA anticodons. Aminoacyl-tRNA ...
The peptidyl-tRNA, which transfers the growing polypeptide to the aminoacyl-tRNA bound in the A/A site, is bound in the P/P site. Once the peptide bond is formed, the tRNA in the P/P site is acylated, or has a free 3' end, and the tRNA in the A/A site dissociates the growing polypeptide chain. To allow for the next elongation cycle, the tRNAs ...

In 1971, Kim et al. achieved another breakthrough, producing crystals of yeast tRNA PHE that diffracted to 2-3 Ångström resolutions by using spermine, a naturally occurring polyamine, which bound to and stabilized the tRNA. [61] For a considerable time following the first tRNA structures, the field of RNA structure did not dramatically advance.
