Introduction: What Is DNA? Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism.

In a technique known as DNA origami, researchers fold long strands of DNA over and over again to construct a variety of tiny 3D structures, including miniature biosensors and drug-delivery containers.

DNA braids, or helix braids, are so called because they resemble the double helix structure of a DNA molecule with two strands that wind around each other like a twisted ladder. They look as ...
