Researcher Photographs DNA Double Helix
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.
