Self-assembly of DNA parallel double-crossover motifs.

ABSTRACT: DNA double-crossover motifs, including parallel and antiparallel crossovers, serve as the structural foundation for the creation of diverse nanostructures and dynamic devices in DNA nanotechnology. Parallel crossover motifs have unique advantages over the widely used antiparallel crossover design but have not developed as substantially due to the difficulties in assembly. Here we created 29 designs of parallel double-crossover motifs varying in hybridization pathways, central domain lengths, and crossover locations to investigate their assembly mechanism. Arrays were successfully formed in four distinct designs, and large tubular structures were obtained in seven designs with predefined pathways and central domains appoximately 16 nucleotides in length. The nanotubes obtained from parallel
