DNA to Protein Translator

Translate a DNA coding sequence into its amino acid sequence using the standard or mitochondrial genetic code.

This tool translates a DNA sequence into its corresponding protein (amino acid) sequence using a codon table.

Translation begins at the first codon and stops at the first stop codon. Both the standard vertebrate genetic code and the vertebrate mitochondrial genetic code are supported.

FAQ

What is DNA translation?

DNA translation is the process of converting a nucleotide sequence into an amino acid sequence using the genetic codon table. Each three-nucleotide codon corresponds to one amino acid.

What is the difference between the standard and mitochondrial genetic code?

The vertebrate mitochondrial genetic code differs from the standard code in a few codons: ATA encodes Met instead of Ile, TGA encodes Trp instead of Stop, and AGA/AGG encode Stop instead of Arg.

Why must my sequence length be a multiple of three?

Codons are read in triplets. A sequence whose length is not divisible by three would produce an incomplete codon at the end, so translation cannot proceed unambiguously.

Can this tool handle long coding sequences?

Yes, the tool supports long DNA coding sequences and is commonly used in research, genome annotation, and bioinformatics workflows.
