Root-mean-square displacements (Å) of G-tetrad guanines over 50 nanosecond MD simulations (compared to minimized reference structures) for two G1 models: (a) G1 with three ammoniums residing in the central cavity between the stacked tetrads, and (b) G1 in the absence of ammoniums in the central cavity).
