▶ Protein Synthesis Animation Video - 2:25 tRNA is joined to the mRNA by a peptide bond. A tRNA moved into the Asite where the codons match the mRNA the Ribosome shifts down by one codon at a time and new amino acids are added one at a time. It cuts off when a stop codon moves into the A site on the mRNA. The mRNA & the amino acid/protein are both released by the ribosome. p-site, A (acceptor) site & E site =Exit
Termination occurs when a stop codon enters the A - site of the ribosome. There are three different stop codons: 1) UAA 2) UGA 3) UAG. A stop codon does not have a corresponding tRNA but instead corresponds to a release factor.

Workflow (depicted in the amount of DNA sequence data generated in trillion of nucleotide bases [Tb] and billion bases [Gb]) to identify the set of overlapping DNA segments that contain stop codon (Amber, Ochre, Opal) reassignments. (Figure by Patrick Schwientek)
Genetic Code RNA by @J_Alves, <p>The genetic code, in RNA letters (U instead of T), and containing amino acids in three representations: full name, 3-letter abbreviation, and 1-letter. Drawn in Inkscape.</p><p>How to read the genetic code: start from the center circle and go outwards. So, if the gene has an AGC, that means amino acid serine. A CGA means arginine. And three of the combinations are stop codons, which don't give any amino acid: TAA, TAG, and TGA.</p>, on @openclipart
