by monitoring the time-dependent density of bound rna polymerase along the relaxed circular dna molecule using this technique , we have been able to demonstrate kinetic evidence for linear diffusion of rna polymerase along dna in a different system from that previously described ( park , c. s. , hillel , z. , and wu , c.-w. ( 1982 ) j. biol . chem . 251 , 6950-6956 ) .
