By creating a more true-to-life representation of DNA's environment, researchers at Northwestern University have discovered ...
Sixty years after scientists described the chemical code of life — an interweaving double helix called DNA — researchers have found four-stranded DNA is also lurking in human cells. .
The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they ...

The double helix, though, is not the only form in which DNA exists. For the first time ever, scientists have identified the existence of a new DNA structure that looks more like a twisted, four ...
ITHACA, N.Y. -- Fifty years after Watson and Crick described the structure of double helix DNA, Cornell University biophysicists are discovering the roles of DNA-binding proteins in much the same ...
DNA is most commonly found in the well-known double helix shape, but new research shows it can take another form. By Avery Thompson Published: Apr 24, 2018 2:42 PM EDT Pixabay ...
Sixty years after scientists described the chemical code of life — an interweaving double helix called DNA — researchers have found four-stranded DNA is also lurking in human cells. The odd ...
In both cases, the mechanism is based on a structural transition of DNA molecules--a change from one conformation (such as the usual double helix) to another. Conventional DNA is a right-handed helix.
