摘要：
DNA packaging into nucleosomes presents a barrier to many motor proteins, including the transcriptional machinery. By unzipping DNA in single nucleosomes, a detailed map at near base pair resolution of histone-DNA interactions is now provided, suggesting that interaction with the two DNA strands is decoupled and that unraveling past the dyad axis of the nucleosome, as might occur when a motor protein passes through, is sufficient to displace histones.
