๐งซCodon Table
The complete standard genetic code โ click any codon for details, or switch to translate mode to convert an mRNA sequence into its amino acid chain.
Free Codon Table
Need to look up a codon fast, or translate a full sequence? Our free Codon Table gives you the complete standard genetic code in one interactive grid. Click any of the 64 codons to see its amino acid, one- and three-letter codes, and side-chain properties โ with start and stop codons clearly marked so you never mix them up.
Search by codon, amino acid name, or letter code to jump straight to what you need. Switch to translate mode to paste in an mRNA sequence and get the full amino acid chain instantly, choosing your reading frame and stopping automatically at the first stop codon โ just like real translation.
Whether you're memorizing the genetic code, working through a molecular biology problem set, or translating a sequence for a lab report, this tool has it covered. No sign-up, completely free. See the About page or the FAQ for more.
