DNA to protein translator
Paste a sequence to see the mRNA, the codons, and the amino acid chain.
From gene to protein
Transcription copies DNA into mRNA, swapping thymine (T) for uracil (U). Translation then reads the mRNA three bases at a time. Each codon codes for one amino acid, and three codons (UAA, UAG, UGA) signal stop.
A coding strand has the same sequence as the mRNA, except T becomes U. A template strand is complementary, so the tool builds the mRNA by pairing each base. Real genes also have introns and untranslated regions that this simple tool doesn’t model.
