(A.5) When taking the variation of C3 no gauge-invariant boundary condition is now needed to get the equations of motion, since the problematic boundary term now cancels against the correction introduced. This correction should actually be introduced for any gauge theory, but usually the ...
If there were no strong steric constraints, electrostatic repulsion might move away from one another the phosphate groups on the two rims of the minor groove (the minimum P–P distance ranges from 0.48 nm to 0.75 nm for the various conformers of the final computation (mean 0.60 nm). These...
