title: [Large scale molecular organization in particles of DNA-poly-L-histidine association].
abstract: The aggregation state of desoxyrinonucleic acid (DNA)-poly-L-histidin (PLH) association depends on both salt concentration and polymerisation degree of the polypeptide. The circular dichroism of DNA associated to PLH is very different from C.D. of DNA alone, and depends on the way in which the mixing has been done. These important modifications of the spectrum have been attributed to a large scale variable organization in the particles of the aggregate.
