Length distribution for T4 DNA molecules extended by the flow of OEMV. The conditions were , of ac electric field, and of laser power (a), and , of ac electric field, and of laser power (b). In both cases, the ratio of the fluorescent dye was /dye. These histograms show the results from measuring 46 (a) and 89 (b) T4 DNA molecules. The bin width is .
