(2004 Shih et al.) Design and synthesis of a rigid DNA octahedron
Reports the design and synthesis of a 1,669-nucleotide, single-stranded DNA molecule that is amplified by polymerases and that folds into an octahedron structure by a simple denaturation-renaturation procedure. Cryo-electron microscopy showed that the DNA strands fold to form hollow octahedra ~ 22 nanometres in diameter. Because the base-pair sequence of individual struts is not repeated in a given octahedron, each strut is uniquely addressable by the appropriate sequence-specific DNA binder.
