'Quadruple helix' DNA discovered in human cells

In 1953, Cambridge researchers Watson and Crick published a paper describing the interweaving 'double helix' DNA structure - the chemical code for all life. Now, in the year of that scientific landmark's 60th Anniversary, ...

Single-DNA images give clues to breast cancer

For the first time, researchers at the University of California, Davis, have watched single strands of DNA being prepped for repair. The research, published this week in the journal Nature, has implications for understanding ...

Novel DNA architecture for nanotechnology

The DNA structure as revealed by Watson and Crick is pivotal to the stability and replication of the DNA double helix. Replacement of the DNA base-pairs with other molecular entities is providing new functions for DNA and ...

Under-twisted DNA origami delivers cancer drugs to tumors

Scientists at Karolinska Institutet in Sweden describe in a new study how so-called DNA origami can enhance the effect of certain cytostatics used in the treatment of cancer. With the aid of modern nanotechnology, scientists ...

Chemists do a double take on the double helix

(Phys.org) -- When most people think of a double helix, they think of DNA structure — a now familiar image thanks to Watson and Crick’s landmark 1953 discovery of the double-stranded molecules of nucleic acids. ...
