Typos in the Genetic Code

Edit a short piece of DNA and watch the protein change; the page counts how many single-letter changes are silent, missense or stop.

How the table was checked

Not independent. The copies below all say they come from NCBI's own file, so agreement shows that my transcription has no slip, not that NCBI's table is right. I could not reach NCBI or any source of a different origin from where this page was built.

Excerpts above are quoted from open-source projects for checking only: Biopython (Biopython License Agreement or BSD 3-Clause) and BioJulia BioSequences.jl (MIT). I could not read BioPerl's licence from here; see its repository.
