The straightforward and consistent pairing of DNA’s nucleotide bases make the molecule a reliable building material. Depending on the sequence, DNA strands can crossover to adjacent helices, creating a branch point. Researchers can develop such connecting pieces, called branched DNA junctions, with 4, 5, 6, 8, or 12 arms, projecting from a central hub at various angles in three-dimensional space.
