Experimental data and theoretical signals calculated with a double-ended zipper (no opening at loop position). Symbols: feature block 1, blue upward-pointing triangles; feature block 2, cyan circles; feature block 3, green downward-pointing triangles; feature block 4, magenta squares; average of all feature blocks, solid black line; calculated signals, solid red line. a) dependence of experimentally observed fluorescent signals on loop length after averaging over all loop positions compared to the calculated fluorescent signals averaged over all loop positions. b) dependence of experimentally observed fluorescent signals on loop position after averaging over all loop lengths compared to the calculated fluorescent signals averaged over all loop lengths.
