Denaturing gel electrophoresis of the fragments from the 3′-exonuclease digestion of AG3(T2AG3)3 I and of its platinated products from reaction with trans-[Pt(NH3)2(H2O)2]2+ 2 (2.1 to 2.4 from Fig. 3). The digestion reaction was conducted with different enzyme dilutions indicated at the top of each lane (e.g. 1 = none, 5 = five times, 30 = 30 times dilution). The numbered purines correspond to the digestion arrests. They were determined from the migration of the corresponding fragments after deplatination by NaCN. The digestion of I gives the reference scale for the migration of the platinated digested fragments.
