    Journal: Radiobiologiia; 1983; 23(5):579-84. PubMed ID: 6651920.
    Abstract:
    On the basis of a quantitative correlation between single--and double-helix fragments of different length within PDN, a study was made of the pattern of distribution of the sites, attacked by nuclease, in the chromatin. It was shown that under the effect of ionizing radiation products of enzymic digestion of the chromatin. It was shown that under the effect of ionizing radiation products of enzymic digestion of the chromatin accumulated in thymocytes due to internucleosome degradation were excised from randomly localized genome sites. The analysis of the reassociation curves did not reveal distinctions in the kinetic complexity of the fractions of PDN and total DNA.
