[Comparison of the effects of actinomycin D on RNA synthesis of young and adult regenerating planarians].
The regeneration of adult planarians is completed inhibited by antinomycin D (AMD), although that of young animals is slightly affected. The proposed hypothesis such as the required mRNA were available prior to section must be revised. In fact, RNA synthesis does occur in spite of AMD in the young. The dose effect, degree of inhibition and rapidity of effect of the inhibitor on RNA synthesis are compared at both ages.
