Free DNA to Protein Translation Tool
Quick Answer
What is this tool? A DNA to protein translator converts a nucleotide sequence into its amino acid sequence using the standard genetic code. It identifies start codons (ATG), stop codons, and translates across all six reading frames for complete open reading frame (ORF) analysis.
How do I use it online? Paste a DNA sequence (raw or FASTA) and select the reading frame — or choose all six — then click Translate. The tool returns the amino acid sequence using the standard genetic code, flagging start and stop codons. Free, no login required.
Uses the standard genetic code (64 codons to 20 amino acids), supports FASTA input, all six reading frames, and stop-codon detection for ORF analysis.

VigyanLLM's DNA to protein translator converts nucleotide sequences into amino acid sequences using the standard genetic code. The tool identifies start codons (ATG), stop codons, and translates across all six reading frames for complete ORF analysis.
| Feature | Description |
|---|---|
| Standard genetic code | 64 codons to 20 amino acids + 3 stop codons |
| All 6 reading frames | 3 forward (+1, +2, +3) and 3 reverse (-1, -2, -3) |
| ORF detection | Identifies start (ATG) and stop codons in each frame |
| FASTA support | Paste sequences with or without FASTA headers |
How DNA to Protein Translation Works
During translation, the ribosome reads messenger RNA (mRNA) three nucleotides at a time, called codons. Each codon specifies one amino acid (or a stop signal). The standard genetic code defines 64 possible codons: 61 encode amino acids and 3 (TAA, TAG, TGA) are stop codons that terminate translation. The start codon ATG encodes methionine and marks the beginning of most protein-coding sequences. This tool simulates that process by reading your DNA sequence in triplets and converting each codon to its corresponding amino acid letter.
What Are Reading Frames?
A DNA sequence can be read in six different frames: three forward (starting at positions 1, 2, and 3) and three reverse (the reverse complement, also starting at positions 1, 2, and 3). Only one frame typically contains the actual protein-coding sequence (the open reading frame, or ORF). This tool shows all six frames so you can identify which one contains your protein of interest. For computational efficiency, the entire process runs client-side in your browser.

Frequently Asked Questions About DNA to Protein Translation
Everything you need to know about using this tool
What is the DNA to protein translation tool?
This tool converts a DNA nucleotide sequence into its corresponding amino acid (protein) sequence using the standard genetic code. It reads the DNA in groups of three nucleotides (codons) and maps each codon to its amino acid.
What are the three stop codons?
The three stop codons are TAA, TAG, and TGA. These do not encode any amino acid but instead signal the ribosome to terminate translation. In this tool, stop codons are displayed as asterisks (*) in the protein sequence.
What is a reading frame?
A reading frame is one of three possible ways to divide a nucleotide sequence into consecutive, non-overlapping codons. Frame +1 starts at position 1, frame +2 at position 2, and frame +3 at position 3. The reverse frames (-1, -2, -3) use the reverse complement strand. Only one frame typically contains the actual protein.
Does this tool support FASTA format?
Yes, you can paste sequences with FASTA headers (lines starting with the greater-than sign). The tool automatically strips headers and whitespace, translating only the nucleotide characters.
Is my sequence data secure?
Yes. All translation happens in your browser. Your DNA sequences are never sent to any server, never logged, and never stored. This is part of VigyanLLM's data sovereignty commitment.
