They are the aminoacyl site (abbreviated A), and the peptidyl site/ exit site (abbreviated P/E). Concerning the mRNA, the three sites are oriented 5' to 3' E-P-A, because ribosomes move toward the 3' end of mRNA. The A-site binds the incoming tRNA with the complementary codon on the mRNA. The P/E-site holds the tRNA with the growing polypeptide ...
A tRNA is commonly named by its intended amino acid (e.g. tRNA-Asn), by its anticodon sequence (e.g. tRNA(GUU)), or by both (e.g. tRNA-Asn(GUU) or tRNA Asn GUU ). [ 19 ] These two features describe the main function of the tRNA, but do not actually cover the whole diversity of tRNA variation; as a result, numerical suffixes are added to ...
Eukaryotic mRNA precursors must be processed in the nucleus (e.g., capping, polyadenylation, splicing) in ribosomes before they are exported to the cytoplasm for translation. Translation can also be affected by ribosomal pausing, which can trigger endonucleolytic attack of the tRNA, a process termed mRNA no-go decay. Ribosomal pausing also aids ...

An aminoacyl-tRNA, with the tRNA above the arrow and a generic amino acid below the arrow. Most of the tRNA structure is shown as a simplified, colorful ball-and-stick model; the terminal adenosine and the amino acid are shown as structural formulas. The arrow indicates the ester linkage between the amino acid and tRNA.
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]
