And no, I don't play an expert anywhere, but I've been tracking developments in molecular biology since I took BioChem in college (notgoing to admit just how long ago). It's one of the top three technologies that will mold the 21st century along with materials science and cybernetics. There's wonders ahead.
Yay! B.A. in Micro/Molecular Biology 1979.
Oh and by the way - methylation anyone....
