A stochastic model for DNA translocation through an electropore

► We present a 1D Fokker-Planck simulation on DNA translocation through an electropore under finite pulses. ► Translocation may occur on the electrophoretic or the diffusive time scale. ► We find a power-law correlation between the probability of successful translocation and the governing parameters. ► The diffusive time scale is used to explain the frequency dependence in AC/DC electroporation experiments. ► This work provides quantitative predictions for further experimental validation and understanding.
