stranded origin, the latter are 1:1 interactions. No interactions were noticed upon mixing oligonucleotideanalogues of different sense of chirality. Modified mixed trans-3-HO A,T sequences display no hybridisation with complementary nucleic acids, nor homocomplex formation. The l-cis all-adenine oligonucleotide hybridises with its RNA complement. Several complexes were investigated by circular dichroism
