The effects of DNA administration on the growth of X-irradiated Xenopus tadpoles.
An easy method for the harmless measurement of the length of tadpoles is described. The results indicate that tadpoles exposed to 3,000 r showed increase in length 20 days following irradiation. The animals exposed to the same or other X-ray doses and administered high molecular homologous and heterologous DNA showed a better rate of growth than the animals exposed to a dose of 3,000 r and not given DNA.
