Abstract

USING ribonuclease as an analytical tool, Gale and Folkes1 have recently brought forward new evidence for the hypothesis that ribonucleic acid plays an important part in protein synthesis2,3. A recent report, by Kaufmann and Das4, that ribonuclease induces mitotic abnormalities in root-tip cells, shows that the enzyme actually can penetrate into living root-tips. These findings led to the present study on the effects of ribonuclease on the metabolism of nucleic acids, protein and respiration in onion root-tips. The experiments have been performed with the technical help of J. Brygier, E. Baltus and F. Vanderhaeghe.
