| Abstract: | A study was made of DNA of different animal species with various radiosensitivity: guinea pig, man, rat and rabbit. It was shown that the radioresistance of the organism increases with increasing relative content of a rapidly reassociating fraction in DNA. As the kinetic complexity of moderately repetitive sequences increases and the total percentage of meaddle and unique DNA fractions grows, the radioresistance of the organism decreases. |
