title: [Cell response to penetration by informational macromolecules].
abstract: A relation is shown between the kinetic for of DNA uptake by the thymocytes (extremal or monotonous), the level of uptake (low or high) and the origin of DNA (hetero-or homologous). Preliminary irradiation of cells promotes a manifestation of  a cytopathogenous effect of the heterologous DNA. The association between the cytopathogenous effect of DNA and that of its information characteristics has been confirmed. The demonstration of cytopathogenous effects of native and degraded DNA was studied as a function of time of their storage. The chromatographic analysis of dispersion of the molecular weights of preparations at different time of their starage allowed a conclusion of the important role played by structure defects in manifestation of cytopathogenous properties of DNA.
