摘要
DNA packaging into chromatin presents a strong barrier to RNA polymerase 11 transcription. In this issue of Molecular Cell, Kireeva et al. describe a minimal system to examine polymerase 11 transcription through a positioned nucleosome and show, surprisingly, that transcription leads to the displacement of an H2A-H2B dimer from the nucleosome without altering nucleosome position.
