The double helix DNA structure is about as iconic as its gets. But geneticists have long speculated about the potential for a quadruple helix to exist — a four-stranded DNA structure. And indeed, ...

If you've seen a representation of a DNA molecule, you've seen the double helix, in which two strands of genetic material are wound together and linked by bonds. In the laboratory, scientists have ...

Many people picture the classic double-stranded helix when picturing a molecule of DNA, but DNA is also capable of forming far more complex structures. Usually though, those structures are not ...

(Nanowerk News) Scientists have identified where a four-stranded version of DNA exists within the genome of human cells, and suggest that it may hold a key to developing new, targeted therapies for ...

The formation of four-stranded DNA has been tracked in living human cells, allowing scientists to see how it works, and its possible role in cancer. DNA usually forms the classic double helix shape ...
