Double-Stranded

That's apropos of absolutely nothing other than molecular biology, a subject for which I have no aptitude. As I (halfheartedly, haphazardly, and reluctantly) studied, I thought that "Double-Stranded" would make a funny funny post title.  It only works, though, if I can tie a sharply witty observation to a biological principle.  But I can't. So I won't. Years of grueling study, and I'm still slow on the uptake.  It's probably genetic.
