Breaking News – ‘Quadruple Helix’ DNA Discovered In Human Cells – 21 January 2013

130120150033In 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, Cambridge researchers have published a paper proving that four-stranded ‘quadruple helix’ DNA structures — known as G-quadruplexes — also exist within the human genome. They form in regions of DNA that are rich in the building block guanine, usually abbreviated to ‘G’. Continue reading
