Roughly six feet of DNA are packed into every human cell, so it is not surprising that our genetic material occasionally folds into odd shapes such as hairpins, crosses and clover leafs. But these structures can block the copying of DNA during cell division, leading to gene mutations that could have implications in cancer and aging.
