Description: Documents the first successful creation of genetically identical frogs that were all members of a clone. Explains how cloning is achieved through inducing a female frog to lay eggs, inactivating the unfertilized eggs' chromosomes, and injecting a nucleus from one tadpole's intestinal cells into each egg. Uses time-lapse photography to show the development of an embryo into an exact genetic duplicate., Documents the first successful creation of genetically identical frogs that were all members of a clone.
