infected cells contained large quantities of viral dna ( more than 10 ( 5 ) genomes per infected cell ) as estimated by dot-blot dna-dna hybridization , and much of the viral dna , when analyzed by southern blot hybridization , was found to be of a 4.8-kilobase-pair duplex monomeric replicative form ( dm dna ) .
