the cloned viral dnas were characterized ( i ) by digestion of the chimeric plasmid dnas with various restriction enzymes followed by comparison of their electrophoretic mobilities in agarose with that of similarly digested uncloned dna , ( ii ) by hybridization of digested chimeric plasmid dnas to 32p-labeled uncloned gbm dna , and ( iii ) by electron microscopy .
