Since the plasmid form of the AquAdvantage DNA construct,
opAFP-GHc2, comprises the complementary deoxyribonucleic acid
(cDNA) sequence of a Chinook salmon GH1 gene as an integrated
transcriptional unit, sequence comparison of the Chinook (C) and
Atlantic (A) salmon GH1 genes was performed in order to ensure
the non-occurrence of cross contaminations.
