Translation - Details A mature mRNA transcript, a ribosome, several tRNA molecules and amino acids are shown. There is a specific tRNA for each of the 20 different amino acids. Below: A ribosome attaches to the mRNA transcript. A tRNA molecule transports an amino acid to the ribosome. Notice that the 3-letter anticodon on the tRNA molecule matches the 3-letter code (called a codon ) in the mRNA. The tRNA with the anticodon "UAC" bonds with methionine. It always transports methionine. Transfer RNA molecules with different anticodons transport other amino acids.

Unformatted text preview: A second tRNA molecule bonds to the mRNA at the ribosome. Again, the codes must match. A bond is formed between the two amino acids. The tRNA bonded to methionine drops off and can be reused later. The ribosome moves along the mRNA to expose another codon (GAU) for a tRNA molecule. The only tRNA molecule that can bond to the GAU site is a molecule with a CUA anticodon. Transfer RNA molecules with CUA anticodons are specific for asparagine. Asparagine is now added to the growing amino acid chain....
