our results indicate that regardless of : ( 1 ) the site of insertion ( either taqi or hpaii ) , ( 2 ) the precise moment of the viral lytic cycle ( from 12 h to 48 h postinfection ) and ( 3 ) the condition of incorporation of the sv40 recombinants to the host cells ( either as minichromosomes or as naked dna , relaxed or negatively supercoiled ) , neither the d ( ca.gt ) 30 nor the d ( cg.gc ) 5 sequence are stable in the left-handed z-dna conformation in the sv40 minichromosome .
