DNA naturally folds itself into cross-shaped structures called cruciforms that jut out along the sprawling length of its double helix. DNA cruciforms are abundant; scientists estimate as many as 500,000 cruciform-forming sequences may exist on average in a normal human genome. Supercomputers have now helped scientists find a surprising link between cross-shaped (or cruciform) pieces of DNA and human cancer, according to a study.
