[Variations in DNA synthesis and the activities of acid and alkaline deoxyribonucleases during regeneration of planaria (Polycelis tenuis)].
Variations of DNA synthesis were established for the first time during planarian regeneration by 32P phosphoric acid incorporation. A first peak of DNA synthesis occurred between the 10th and the 18th hour after sectioning (maximum at 12 hrs.). Subsequently, DNA synthesis increased again progressively after the 24th hour to a plateau between 48 and 72 hrs. after regeneration. Simultaneously, variations of alkaline and acid DNases were determined.
