title: The presence of the 30 nm filament structure of chromatins in intact chicken erythrocytes observed by 31P NMR.
abstract: A 31P NMR spectrum of chicken erythrocyte chromatins in vivo was obtained. The spectrum was characterized by examining the spectra of isolated nuclei and nondigested chromatins under various conditions. The results have shown that most chromatins in chicken erythrocyte nuclei assume the 30 nm filament structure as a second step of condensation of DNA in vivo.
