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 discovered in 1953 – two strands wound around each other. Several other structures have been formed in test tubes, but this does not necessarily mean they form within living cells. “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 […]
