Translation: the process whereby the genetic code carried by mRNA is read and used to construct proteins. This process is carried out by ribosomes. The ribosomes recruit appropriate 4S or transfer RNAs (tRNAs) which are (conceptually) molecules with an amino acid at one end and an "anticodon" at the other. 1/12/2010 Reinhard Neier 10 Neier/12/01/2010

The large subunit creates the peptide bonds and the small subunit has key roles in initiating the biosynthetic process and in controlling the fidelity of codon-anti-codon base pairing. The ribosome contains three tRNA binding sites, designated the A (aminoacyl), P (peptidyl) and E (exit), which are located on both subunits. During the elongation cycle both ribosomal subunits work together to translocate all three tRNAs molecules together with the associated mRNA chain by precisely one codon. In this motion each of the tRNA molecules passes through the three ribosomal binding sites, from A- to P-to E-site.

You can see how a tRNA interacts with the 30S subunit because of anticodon-codon bonds; and it interacts with the 50S subunit throught the positioning of the attached amino-acid for catalysis.

In each case, you can see the three tRNA binding sites and you can easily imagine how a tRNA moves through the ribosome from the A-site to the P-site to the E-site.

The ribosome is the cellular organelle catalyzing the translation of genetic code into proteins. It is a protein/RNA assembly arranged in two subunits that associate for performing protein biosynthesis. The prokaryotic large ribosomal subunit, which migrates with sedimentation coefficient of 50S and is of molecular weight 1.5 mega Dalton, contains 3000 nucleotides in two RNA chains and ~35 proteins. The smaller ribosomal subunit, which migrates as 30S and is of 0.85 mega Dalton, contains 1500 nucleotides in one RNA chain and ~20 proteins.

In 2001, several research groups were able to get structures of a ribosome—a very complex nucleic acid structure and an enormous protein-RNA complex that is responsible for synthesizing proteins. These images, produced by Harry Noller at the University of California Santa Cruz, at the , England, and Thomas Steitz at Yale University are worthy of a Nobel Prize.

Molecular model of a ribosome, Molecular model of a bacterial ribosome showing the RNA and protein components in the form of ribbon models. In the large (50S) subunit the 23S RNA is shown in cyan, the 5S RNA in green and the associated proteins in purple. In the small (30S) subunit the 16S RNA is shown in yellow and the proteins in orange.

Molecular model of a ribosome: The three solid elements in the centre of the ribosome, coloured green, red and reddish brown are the transfer RNAs (tRNAs) in the A, P and E sites respectively. The anticodon loops of the tRNAs are buried in a cleft in the small subunit where they interact with mRNA. The other ends of the tRNA, which carry the peptide and amino acid, are buried in the peptidyl transferase centre of the large subunit, where peptide bond formation occurs. 1/12/2010 Reinhard Neier 21 Neier/12/01/2010
