Nuclear Transplantation and the Analysis of Gene Activity in Early Amphibian DevelopmentAmphibian eggs are large and tolerant to the injection of small pipettes. For this reason they are particularly well suited for microinjection experiments. This paper discusses certain types of injection experiments that have proved informative in the analysis of gene activity in development.

The gibberellins are synthesized in the embryo tissues after germination begins and have as their principal target tissue the cells of the aleurone layers (Yomo and Varner, 1971). These aleurone cells produce and secrete the hydrolases that hydrolyze the s
