Popis: Here the authors used single-molecule imaging and manipulation to study the mechanical effects of transcription factor Sox2 co-condensation with DNA and chromatin. They found that Sox2 condensates exert a high level of mechanical stress on DNA, but this stress is dramatically attenuated by nucleosomes assembled on the DNA.
