(a) Experimental difference in intensity-current curves (four averaged retraction curves each) after hybridization of a 50-mer to the 200-mer, where the red curve is for fully ssDNA and black curve is for the partially hybridized strand. The scale is based on the initial intensity I0 set to 1 at z = 0. I0 values were obtained from fits to Equation (5) and (8) respectively. Lines indicate fits to data. (b) Plot of (a) in terms of extension versus force using the parameters from fitting. The standard deviations of the averaged curves is less than their respective marker sizes.
