Abstract

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.

摘要

通过掺入32P磷酸首次确定了涡虫再生过程中DNA合成的变化。DNA合成的第一个峰值出现在切片后的第10至18小时之间(12小时时达到最大值)。随后,在第24小时后DNA合成再次逐渐增加,在再生后的48至72小时之间达到平稳状态。同时,还测定了碱性和酸性DNA酶的变化。
