abstract：:The cancer drug daunomycin is an effective inhibitor of the B leads to Z transition in poly d(G-C) in 4 M NaCl. Both the rate and extent of the B leads to Z transition are decreased by the drug, as judged by equilibrium and kinetic studies. Daunomycin can, under some conditions, convert Z form DNA back to B form. Drug...
