Folding crystallization of DNA. Circular dichroism studies.
CD spectra of DNA monocrystals are extremely different from spectra of psi-DNA or DNA-histone H1 or DNA-polylysine complexes. They are discussed to be dependent on the supramolecular organization of DNA in the condensed form, and they are not in contradiction to the previously proposed seven folding model of DNA in chromatin. Conclusions are drawn with regard to the interpretation of chromatin CD spectra.
