title: [Radiosensitivity of coding and noncoding DNA sequences of various organisms].
abstract: Relationship between pyrimidine distribution patterns and radiosensitivity (Z) of DNA molecules of different species was derived by computer analysis of recurrence frequency of pyrimidine clusters. Blocking factors (beta) and Z for coding and non-coding DNA sequences of species from different taxonomic classes have been calculated within a new model. The radiosensitivity of coding DNA sequences practically does not vary whereas Z values were increased during evolution from simplest to higher organisms. The beta and Z values calculated for several groups of individual genes were shown to vary considerably.
