abstract：:We have used gel retardation analysis to show that human DNA topoisomerase IIbeta can bind a 40 bp linear duplex containing a single DNA topoisomerase IIbeta cleavage site. Furthermore, we demonstrate for the first time that human DNA topoisomerase IIbeta binds to four-way junction DNA. This supports previous suggesti...
