Irradiated L strain cells were treated with highly polymerized isologous deoxyribonuclein acid (DNA), and resuits show that the irradiated cells survive better if they are treated after irradiation. In irradiated cuitures treated with 80 μ g DNA/ml only 10% of the irradiated cells died in a 4-day interval following irradiatron, whereas in nontreated cuItures for the same time-interval about 50% of the irradiated cells lost the capacity to divide. The recovery effect seems to depend upon the amount of DNA added to the irradiated cuItures. Results of the effect with nificant survival is obtained with 60 and 80 μ g.
