Where this comes from

Abstract

Ngo et al. use single-molecule methods to show that DNA can be more readily displaced from one side of a nucleosome relative to the other side. This unexpected mechanical asymmetry may offer a path of least resistance, allowing RNA polymerases to traverse nucleosomes if they approach from the correct direction.
