Schematic representation of oligonucleotide-based monomers, OM's. Short oligonucleotides are linked by a spacer (left), and reversible base pairing defines the main chain of a reversible polymer that resembles beads on a string (far right), where the “beads” are rigid DNA duplexes and the “string” is the intervening spacer. The oligonucleotide sequence determines the thermodynamics and kinetics of the association, and the spacer determines the overall flexibility of the chain and spacing between reversible interactions. See ref. 62.
