Changes in the kinetics of rabbit thymus DNA re-association in various time periods after gamma-irradiation

A distinction has been detected in the kinetic curves of the control and in vivo irradiated DNA at the site of the reassociation of moderate and unique genome fractions. This distinction increased with increasing Cot. It was shown that the thermostability decreased and the profiles of DNA duplex thermoelution changed in irradiated rabbits as compared with intact ones.
