Abstract

A polymer composition is disclosed composed of morpholino subunit structures linked together by uncharged, chiral linkages, one-three atoms in length. These chiral linkages join the morpholino nitrogen of one subunit to the 5' exocyclic carbon of an adjacent subunit. Each subunit contains a purine or pyrimidine base-pairing moiety effective to bind by hydrogen bonding to a specific base or base-pair in a target polynucleotide.
