Breaking bonds: Double-helix unzipping reveals DNA physics Using previously developed theoretical and mathematical models, researchers used information on the speed of the process of DNA unzipping ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...

When most of us think of DNA, we think of that iconic double helix shape. But when you zoom out, DNA gets a lot more complicated. "When Watson and Crick described the DNA double helix, they were ...

Move Over, Double Helix: A New Form of DNA Has Just Been Discovered. ... scientists have long suspected there’s another type of DNA that looks quite different from the famous Watson-Crick model.

Watson and Crick built an incorrect triple-helix model of DNA in 1951, after Watson saw a lecture by Franklin where she showed crystallographic X-ray images she had taken of DNA.

In 1953, Watson and Crick came up with the standard double-helix model of DNA. Two twisted polynucleotide chains create a double helix held together by nucleotide base pairs.

As such, whereas all double-stranded DNA molecules repel one another somewhat, the ridges and grooves of identical helices fit together better than with those of other DNA, making it easier for ...

The double helix model of DNA may not be at the center of everything after all, with British scientists discovering a natural four-standed helix. Skip to main content. Menu ...
