Also known as trinucleotides. A codon is made up of three <a href="Nucleotides">nucleotides</a> found in <a href="DNA">DNA</a> or <a href="MRNA">mRNA</a>, and codes for one specific <a href="Amino acids">amino acid</a>. The order of these three <a href="Nucleotides">nucleotides</a> is unique and vitally important in the coding of its <a href="Amino acids">amino acid</a>.ALBERTS, B. et al. (2008) Molecular Biology Of The Cell. 5th edition. New York: Garland Science.

An <a href="Amino acids">amino acid</a> can be back-translated from a codon sequence by using the <a href="Codon Wheel">codon wheel</a>.

In some instances, there can be more than one codon which corresponds to the same <a href="Amino acids">amino acid</a>. Genetic Code Supports Targeted Insertion of Two Amino Acids by One Codon Anton A. Turanov, Alexey V. Lobanov, Dmitri E. Fomenko, Hilary G. Morrison, Mitchell L. Sogin, Lawrence A. Klobutcher, Dolph L. Hatfield, and Vadim N. Gladyshev (9 January 2009) Science 323 (5911), 259. [DOI: 10.1126/science.1164748] One codon can code for two different amino acids within the same gene, with the choice determined by an RNA structure in an untranslated region.
