Nucleosomes tightly wrap ~147 DNA base pairs around an octamer of histone proteins, but how nucleosome structural dynamics affect genome functioning is not completely clear. Here authors employ all-atom molecular dynamics simulations of nucleosome core particles and observe that octamer dynamics and plasticity enable DNA unwrapping and sliding.
