Über die Geschwindigkeit der Protein-Synthese in kernlosen und kernhaltigen Zellen von Acetabularia

Abstract

Comparing nucleate and enucleated cells of Acetabularia mediterranea and A. crenulata, the question was reexamined whether or not there is a temporary stimulation of protein synthesis in enucleated cells as reported by BRACHET and coworkers. The data presented here clearly show that there is no higher protein synthesis in enucleated cells than in nucleate ones: The rate of protein formation of enucleated cells is at most equal to that of nucleate cells during the first time following enucleation. It is concluded, that there is no inhibitory effect of the nucleus on protein synthesis.
