to understand the mechanism of action of nuclear factor i , we have constructed , by recombinant dna techniques , origins of replication in which the adenovirus type 5 nuclear factor i binding site ( fib site ) has been replaced by a fib site isolated from human genomic dna ( gronostajski , r. m. , nagata , k. , and hurwitz , j .
