Abstract excerpt

Antitumor drugs, such as anthracyclines, interfere with mammalian DNA topoisomerase II by forming a ternary complex, DNA-drug-enzyme, in which DNA strands are cleaved and covalently linked to the enzyme. In this work, a synthetic 36-bp DNA oligomer derived from SV40 and mutated variants were used...
