dc.description.abstractWe use confocal fluorescence microscopy to study the conformation of single DNA molecules endtethered to a solid substrate. The segment distribution ρ(z) measured for chains with contour lengths 15.4 μm ≤ L ≤ 59.4 μm as a function of the distance from the substrate z can be scaled onto a master curve depending only on the scaled distance z/Rg, in quantitative agreement with theoretical predictions for end-tethered polymers in a good solvent. The scaling of the radius of gyration Rg ~ L shows the presence of excluded-volume interactions between the charged DNA segments. Independent measurements of Rg from end-segment distributions are in good agreement with values obtained from the segment distributions and provide evidence that the radius of gyration of end-tethered chains in a good solvent is identical to that of the free chain.eng
