And even more interesting, an universal constructor capable to reproduce itself WITH a non trivial payload to be assembled too. And here we are with the germline assembling a transitory somatic line for the better preservation of the core, the germline, from generation to generation, a synthetic version of the Weismann theory of the cellular evolution of life.

There was an article here yesterday showing the imaging of DNA, and that took an electron microscope, which uses shorter wavelengths than even ultraviolet. In years to come this will keep Moore's Law on track up to the time computer circuits are assembled from carbon nanotubes and graphene and organic memristors. In fact, this might even be the technique used to do that.
