DNA photographed for first time

Washington, Mon, 03 Dec 2012 ANI

Washington, December 3 (ANI): Humans have for the first time captured direct photos of DNA.

A Discovery News report has revealed that Enzo di Fabrizio, a researcher at the University of Genoa, Italy, 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. (ANI)
