Researcher Photographs DNA Double Helix

Enzo di Fabrizio, a researcher at the University of Genoa for the first time has developed a technique that pulls strands of DNA between two miniscule silicone pillars and then photographs them via an electron microscope.

Meanwhile New Scientist has stated that the technique actually photographs seven strands of DNA wrapped into what's referred to as a "cord." That's because the electrons emitted by the microscope are too powerful to take a picture of a single strand without destroying it.

But Di Fabrizio said that using a lower-power electron scope could likely solve the problem.

"With improved sample preparation and better imaging resolution, we could directly observe DNA at the level of single bases," Huffingtonpost quoted him as saying.
