What was John Gurdon's experiments and what did the results signify? - In his frog experiments he tested whether a differentiated nuclei retained the genetic information to produce a new individual. Test whether a differentiated cell had the same genome as a one cell zygote. He took the haploid egg of a normal adult green frog and enucleated it to produce a enucleated egg. He then took a fully differentiated skin cell of a albino adult frog and removed the diploid nucleus and transplanted i...
