Four-stranded DNA discovered


Image based on an X-ray crystal structure of a G-quadruplex formed from the DNA sequence found in human genomes.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. .  Researchers think the four-stranded DNA could be a target for personalized medicine in the future. If they could block these odd ducks perhaps they could stop the rapid cell division of cancer cells.
