Ultra-sensitive microscope reveals DNA processes * 14:02 15 November 2005 * NewScientist.com news service * Gaia Vince A new microscope sensitive enough to track the real-time motion of a single protein, right down to the scale of its individual atoms, has revealed how genes are copied from DNA – a process essential to life. The novel device allows users to achieve the highest-resolution measurements ever, equivalent to the diameter of a single hydrogen atom, says Steven Block, who designed it with colleagues at Stanford University in California. Block was able to use the microscope to track a molecule of DNA...
