摘要：

The spatial distribution of P within active fraction [calf thymus] nucleosomes reveals that the path of the DNA is consistent with 1 3/4 turns of DNA supercoiled around the outside of the protein core. This P distribution, obtained with an imaging electron spectrometer in a conventional transmission electron microscope, simultaneously establishes new limits of sensitivity for elemental microanalysis.
