Identifying Open Reading Frames (ORFs) in dsDNA

    The 44 bp example above is taken from the complete mitochondrial DNA sequence of an Atlantic Cod (Gadus morhua). One or more stop triplets (*) occur in five of the six reading frames (all except the second frame in the lower strand, read 5'3'). This open reading frame (... F T G A L I L M I A H G L A ....) is part of the code for a subunit protein of the enzyme cytochrome oxidase  .

     Important note: The above example uses the mitochondrial DNA code, which  has different stop codons from the 'Universal' code.
