Back before I realized that cartoons were merely thirty minute commercials for toys I would later harass my parents to purchase for me, I watched the same animated shows everyone else did, including G.I. Joe. Periodically, when the toymakers realized they needed to introduce a new line of toys, they would begin a new season of the cartoon and introduce a whole host of new characters, each with its own accompanying "action figure." And so it was with Serpentor, the new leader of the terrorist organization, Cobra, who was introduced in a five part episode entitled, "Arise, Serpentor, Arise!" This new super villain was genetically manufactured by the villainous Dr. Mindbender, who dispatched his evil forces across the globe to rob the graves of famous military leaders and tacticians so that he might create his own super military leader from their DNA. Wikipedia suggests that this was part of the second season of the G.I. Joe cartoon, which aired sometime in 1985 or 1986. (I suspect it was 1986, as both the Wikipedia entries for Serpentor and Dr. Mindbender indicate those action figures were released that year.). Pictured above is the cover of G.I. Joe #49, which depicts Destro and Dr. Mindbender making off with a corpse for this purpose. In the cartoon, Dr. Mindbender, in explaining the scheme he had hatched, specifically mentions DNA and the source of the acronym, and I remembered it, making myself look smart in class later that year. Who knew? The best part: I never had to reveal the source of my knowledge, for even then, I knew that I would have regretted that admission.
In fact, thanks to the power of the YouTubes, I have found the exact moment of the G.I. Joe miniseries at issue. See below, and fast forward to about 1:50 in the video:
