One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double helix. Double-strand breaks are among the most difficult forms of DNA damage ...

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. .

An artist's impression shows the famous double-helix DNA structure. Now, scientists have found a four-stranded twisted "knot" structure in human cell lines.

For the first time, scientists have detected a DNA structure inside living human cells that looks more like a four-stranded knot than the elegant double helix we learned about in school.

The human genome is usually formed as a double helix, but DNA can assume other configurations such as the four-stranded structure. Four-stranded DNA structures are known as G-quadruplexes (G4) and ...
