    "abstract": "The structure of DNA in the nucleosome core particle is studied using an\nelastic model that incorporates anisotropy in the bending energetics and\ntwist-bend coupling. Using the experimentally determined structure of\nnucleosomal DNA [T.J. Richmond and C.A. Davey, Nature {\\bf 423}, 145 (2003)],\nit is shown that elastic correlations exist between twist, roll, tilt, and\nstretching of DNA, as well as the distance between phosphate groups. The\ntwist-bend coupling term is shown to be able to capture these correlations to a\nlarge extent, and a fit to the experimental data yields a new estimate of G=25\nnm for the value of the twist-bend coupling constant.",
