  • When double helical DNA is exposed to conditions favoring partial melting in polyacrylamide gels, its electrophoretic mobility undergoes a sharp cooperative transition, resulting in a large reduction in mobility. In the present experiments, where the transition is effected at a uniform temperature of 60 degrees C in a concentration gradient of a urea-formamide mixture, each Eco RI fragment of lambda or E. coli DNA exhibits the mobility transition at a characteristic concentration of the… CONTINUE READING
