Before revision:  109, 228101, 2012) the elastic properties of DNA were studied by molecular dynamics (MD) simulations . Two important conclusions were made: (i) the computed bending and twisting rigidities of DNA agree well with experimental data , and (ii) for lengths of a few helical turns, DNA dynamics exhibits long-range correlations in qualitative difference from the worm-like rod (WLR) model.
After revision:  109, 228101, 2012) the elastic properties of DNA were studied by molecular dynamics (MD) simulations predict DNA rigidity close to experimental data and confirm one scenario of such breakdown, namely, that for lengths of a few helical turns, DNA dynamics exhibits long-range correlations in qualitative difference from the worm-like rod (WLR) model.
