Creating a genetic program to crinkle DNA into the perfect shape can appear to be a scientific stunt. But DNA origami is more than a molecular magic trick. In this excerpt from a 2007 TED lecture, Paul Rothemund describes the science behind the work– how a chain– based on its sequence– becomes a two-dimensional shape.
Last night I realized how long it’s been since I last folded a paper crane. The documentary, Between the Folds, allows origami to explode into this beautiful world of artistic creations and amazing patterns and complexity driven by algorithms– sequences of mathematical instructions– ranging from simple to astronomically complex. The funny thing is that on
