What is the RNA to Protein Translator?
Translate RNA sequences into amino acid chains using the standard (universal) genetic code. Choose reading frame 1–3, translate the full sequence or an ORF from the first AUG to a stop codon, and view a codon-by-codon breakdown. Supports FASTA input. Free, private, and runs instantly in your browser.
How to use the RNA to Protein Translator
- Paste an RNA sequence (A, U, G, C — T is accepted as U).
- Choose full-sequence translation or ORF mode (first AUG to stop).
- Select reading frame 1, 2, or 3.
- Read the one-letter protein sequence and codon table.
- Copy the protein or full translation summary.
Common use cases
- Translating an mRNA sequence to a peptide for homework
- Finding the protein encoded from the first AUG
- Comparing reading frames on the same RNA sequence
Frequently asked questions
- What genetic code is used?
- The standard universal genetic code used by most organisms. AUG codes for methionine (start), and UAA, UAG, and UGA are stop codons.
- What is ORF mode?
- Open reading frame mode finds the first AUG in the selected frame and translates until the first stop codon, which is typical for predicting a protein coding region.
- What are reading frames?
- RNA is read in non-overlapping triplets (codons). Frame 1 starts at base 1, frame 2 at base 2, and frame 3 at base 3. The same RNA can give different proteins in different frames.
- How are stop codons shown?
- In full-sequence mode, stop codons appear as * in the protein output. In ORF mode, translation ends at the first stop and the stop is not appended.
- Is sequence data uploaded?
- No. Translation runs locally in your browser.
