Whether this bizarre form of DNA existed in cells and had any function, and what that might be, was hotly debated for nearly half a century. But research has recently confirmed its biological ...

The left-handed Z-DNA double helix is held together by traditional Watson-Crick base pairs, but unlike righthanded B-DNA, which has major and minor grooves between the twists of its sugar-phosphate ...

We have built a prototype set of Borromean rings from DNA by mixing B-DNA and Z-DNA in a specific fashion. In a second use of Z-DNA, we have constructed a DNA nanomechanical device. The device ...

What did the duo actually discover? Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case.
