Enjoyed that link, tantalus. I have sometimes wondered what would happen if you changed the sugar group, but this is the first I've heard of it being explored. I assume there is some kind of change of scale. This has several interesting topics wrapped up in it: evolution, the way they altered the sugar groups and the geometry, all the unknowns and potentials of synthesizing DNA, the "interspecies" hosting of the synthetic onto the natural DNA, and all the applications, from biotech to medicine. Awesome.
