Caltech Scientists Control Complex Nucleation Processes Using DNA Origami Seeds
April 8, 2009
The construction of complex man-made objects--a car, say, or a pizza--almost invariably entails "top-down" processes, with the structure of the thing being built imposed from outside. Biological objects instead use a "bottom-up" approach, with order imposed from within the object being made, so it "grows" according to a built-in design.
