It's not just the double helix! For the first time, scientists have identified the existence of a new DNA structure never before seen in living cells. The discovery of what's described as a 'twisted knot' of DNA in living cells confirms our complex genetic code is crafted with more intricate symmetry than just the double helix structure everybody associates with DNA – and the forms these molecular variants take affect how our biology functions. "When most of us think of DNA, we think of the double helix," says antibody therapeutics researcher Daniel Christ from the Garvan Institute of Medical Research...
