Addendum: An earlier version of this article incorrectly stated that a single strand of DNA had been imaged — including its characteristic double-helix. Rather, the image is of a bundle of DNA ...

The first direct images of the DNA double helix have been taken using electron microscopy.. In a study published in the journal NanoLetters, Enzo di Fabrizio, head of the Nanostructures Department ...

It’s tiny—that little scale bar in the bottom right corner measures just 20 nanometers—but it definitely shows the characteristic double helix that makes DNA iconic.

DNA's double-helix structure is on display for the first time in this electron microscope photograph of a small bundle of DNA strands. ... Italy, snapped the picture using an electron microscope.

"When Watson and Crick described the DNA double helix, they were looking at a tiny part of a real genome, only about one turn of the double helix," University of Leeds researcher Sarah Harris says ...

It's worth mentioning again and again: a tremendous amount of information on the Internet is wrong. This epidemic of incorrectness extends to the very structure of DNA: the double helix. That's right, ...

But the sole experimental evidence on which the double helix structure is based is an X-ray diffraction picture of DNA (Photograph 51) taken by PhD student Raymond Gosling working under ...

Dr Harris said: "When Watson and Crick described the DNA double helix, they were looking at a tiny part of a real genome, only about one turn of the double helix. This is about 12 DNA 'base pairs ...

Since the discovery of the double helix structure of DNA nearly 70 years ago, scientists have worked to understand how the two strands of DNA are opened to access the genetic information they ...

The double-helix structure has practically become synonymous with DNA, but it isn't the only way long strands of genetic information squeeze themselves into a tight space. When a double-strand of DNA ...

The book is "The Secret of Life: Rosalind Franklin, James Watson, Francis Crick, and the Discovery of DNA's Double Helix." Howard Markel, always great to see you. Dr. Howard Markel: ...
