The positive control with an internally induced twist due to additional base pairs in each helix (these additional base pairs lead to a net torque in each helix and therefore a macroscopic deformation of the structure) displays much larger angles. The population around zero is probably caused by deformed structures which had no second arm but could not be visually excluded. This results in many angles around zero. The other population around the finite angle is now the more spread structure. Here the angle of the positive control is shifted to higher values by approximately a factor of 2 because of the induced twist. So in principle this way of measuring the deformation of our structure in dependence of induced stress works.
The measured angles φ for negative and positive control, $\phi_{neg} \approx 9$° and $\phi_{pos} \approx 21$°, can be related to a torsion α of the base according to the [http://openwetware.org/wiki/Biomod/2011/TUM/TNT/Project#Twist_of_the_Base theoretical considerations for the base twist]: +
