I found this interesting computer animation representing DNA functions in cells. My questions: 1) How precisely can we actually magnify cell functions, and what is preventing us from peering in as closely as depicted in the video (keeping in mind that I know it's probably technologically infeasible to construct an atomic sized camera that can zip around and record what's going on)? 2)I've seen photographs of individual atoms, so why is it that when I search for magnified images of cells, it's never at the atomic level? 3)Have florescent dyeing techniques been able to resolve any of these functions at the atomic scale? 4) Would high speed video from a powerful microscope (shooting at perhaps 10,000-50,000 frames per second) be able to provide useful temporal information about the process of DNA replication?
