There is a broader implication though: It's known that many drugs come from or are discovered in naturally occuring plants and then synthesized. If the genetic basis for these types drugs can be discovered and replicated, you could turn the human body into it's own pharmacy. Maybe synthesizing salicin internally could be as effective as taking aspirin? (and less irritating for your stomach) Or maybe if the fundamental genetic operations that synthesize chemicals/proteins is discovered (the microcode of cells?) you could even synthesize chemicals that don't occur naturally. Perhaps in the future a "pharmaceutical organ" will be hacked into the human body specifically for this purpose.
Of course there's the other side to this, where people will want to synthesize certain chemcials in opiates or marijuana ... Fun to speculate about, at least!"
