OriGene Codon Table Tool

A codon is a sequence of three nucleotides found in DNA or RNA that corresponds to a specific amino acid or stop signal during protein synthesis. The codon table, also known as the genetic code, is a systematic way of mapping these codons to their corresponding amino acids or stop signals. This codon tool can be used to translate a standard genetic code as well as mitochondrial and nuclear genetic codes into a sequence of amino acids for multiple species.
