Living things use DNA to store the genetic information that makes each plant, bacterium, and human being unique. The reproduction of this information is made possible because DNA's nucleotides—A's and T's, G's and C's—fit together perfectly, like matching jigsaw puzzle pieces. Engineers can take advantage of the matching between long strands of DNA nucleotides to use DNA as a kind of molecular origami, folding it into everything from nanoscale smiley face artwork to serious drug-delivery devices.
