Structure of DNA rewritten as scientists find genetic ‘towers’ in human cells – Telegraph.co.uk
Scientists discover that the twisting, ladder-like structure of our genes can sometimes have two extra arms, forming a four-sided tower
A team of researchers from the University of Cambridge, Imperial College London and Leeds University invented a fluorescent marker that can attach to a quadruple helix, allowing it to be seen for the first time so experts can begin discovering what role it plays in cells.
Lead researcher Dr Marco Di Antonio, of Imperial College London, said: “For the first time, we have been able to prove the quadruple helix DNA exists in our cells as a stable structure created by normal cellular processes.
