About this tool
Enter a DNA or RNA sequence and this tool translates it into the corresponding protein using the standard genetic code. Any T is treated as U, and non-nucleotide characters are removed, so you can paste raw or formatted sequences. The work is done entirely in your browser.
Translation starts at reading frame 1, 2 or 3 (an offset of 0, 1 or 2 bases). The sequence is then read three bases at a time; each of the 64 codons maps to one amino acid or a stop signal (UAA, UAG, UGA). Optionally translation can begin at the first AUG start codon and it always halts at the first stop codon. A trailing group of one or two leftover bases is reported as an incomplete final codon.
The protein is shown in single-letter or three-letter code, whichever you choose, and is copyable. For example AUG UUU UAA translates to Met-Phe-Stop, i.e. the peptide MF followed by a stop at codon 3.
