Abstract
By using appropriately modified oligonucleotides, a gap-structure is formed in substrate DNA, and 2-6 ethylenediamine-N,N,N'-triacetate residues are placed near this gap. When these composites are treated with homogenous Ce(IV)/EDTA complex, the phosphodiester linkages in the gap-site are selectively hydrolyzed at much greater rates than achieved previously by using unmodified oligonucelotides.
