Advances in single-molecule research 'revolutionary, not evolutionary'

Not long ago, the idea of conducting an experiment on a single strand of DNA seemed far beyond the realm of science. But thanks to rapid advances in microscopy in the last decade, researchers can now watch a single gene being transcribed from DNA—one atom at a time—or observe the activity of a protein molecule as it moves inside a living cell.
