Author Correction: Information-based autonomous reconfiguration in systems of interacting DNA nanostructures.

The original version of this Article omitted a reference to previous work in 'Stojanovic, M. N. & Stefanovic, D. A deoxyribozyme-based molecular automaton. Nat. Biotechnol. 21, 1069-1074 (2003)'. This has been added as reference 42. The following has been added after the third sentence of the fifth paragraph of the Discussion: 'Integration could also allow more sophisticated information processing, for example as shown by the classic deoxyribozyme-based automaton that plays tic-tac-toe42, to direct structural reconfiguration (Supplementary Discussion)'. This has been corrected in the PDF and HTML versions of the Article.
