Description:
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.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bazett-Jones, D P -- Ottensmeyer, F P -- New York, N.Y. -- Science. 1981 Jan 9;211(4478):169-70.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7444457" target="_blank"〉PubMed〈/a〉
