How This DNA/RNA to Protein Translator Works

This calculator uses the standard genetic code to translate DNA or RNA codons into one-letter amino acid codes. RNA sequences are normalized by converting U to T before translation, so AUG and ATG are both translated as methionine (M).

Translation Rules

  • Frame 1 starts translation at nucleotide 1, frame 2 at nucleotide 2, and frame 3 at nucleotide 3.
  • Reverse complement mode reverses the submitted sequence and applies the complement rules before translation.
  • Incomplete trailing codons are not translated and are reported as warnings.
  • Codons containing N or another unresolved nucleotide are translated as X.
  • Stop codons can be shown as *, trimmed at the first stop, or removed from the output.
  • All parsing and translation runs in your browser; uploaded sequence files are not sent to Neurosnap servers by this viewer.

For reverse translation, we suggest using Neurosnap's codon optimization tools because the codons you want to use are highly dependent on the host and desired research objectives. Use our codon optimization tools to design host-aware coding sequences.
