The Genetic Code

The genetic code is the set of correspondences between the nucleic acid triplets (codons) and amino acids in the primary sequences of ribosomaly produced proteins. The code is universal. With the exception of some small variabilities, this rule prescribes how to decode genes into proteins in all organisms on Earth (and beyond?). For example, every protein synthesis on the ribosome starts with AUG codon, which encodes methionine (Met), CCA will code for proline (Pro), CAC for histidine (His), GUA for valine (Val), etc. The amino acids encoded by the gene sequences are called coded or canonical amino acid, thus obeying the rule, canon. Each of these amino acids may have its own peculiarities. We have summarized some interesting information and references for the canonical amino acids in dedicated sections. Just click away.
