The Stop Codon

The stop codon is a codon that indicates the end of a gene. The three known stop codons are TAA, TAG, and TGA. In protein translations of DNA, a stop codon is indicated by an asterisk (*). The space between two stop codons in a genome is called an open reading frame. All protein encoding genes must be at the end of an open reading frame. If a stop codon is found inside a gene, it is an indication that the gene has been called incorrectly.
