caption: (A--C) Distribution in contour length of DNA (1000 bps) molecules with Hfq--CTR to bp ratio of 1:50 (blue),1:1 (red) and 10:1 (green). (<PERSON>) Orientation correlation function of the tangent vectors at a pair of points separated by distance L along the contour. The closed symbols are the experimental data obtained by averaging 34--49 molecules. The solid lines are exponential fits.
