: consisted in finding 2 variantsw of Xenopus one with 1 nucleole 
: and the other with 2. He then took the nucleous of ONE cell 
: (intestinal, but then he also did it with neurons (these do not 
: normally divide!!!!!)) and placed it inside an irradiated egg 
: cell. The donor had 1 nucleole and the the recipient 2 (or 
: viceversa). That way he KNEW where the genetic material came

: healthy frogs!!!.

: It is the first cloning experiment I know of and he should have 
: gotten the Nobel for that one, but...

: Beatiful papers if you are interested in research in general and 
: Xenopus in particular.
