Abstract
The spatial distribution of phosphorus within active fraction nucleosomes reveals that the path of the DNA is consistent with one and three-fourths turns of DNA supercoiled around the outside of the protein core. This phosphorus distribution, obtained with an imaging electron spectrometer in a conventional transmission electron microscope, simultaneously establishes new limits of sensitivity for elemental microanalysis.This publication has 3 references indexed in Scilit:
