State
Reproductive cloning produces a genetically matched organism using somatic cell nuclear transfer: transferring a donor's diploid nucleus into an enucleated egg, a technique also usable therapeutically.
Show
Dolly the sheep, born in 1996, developed from a donor nucleus transferred into an enucleated egg and implanted in a surrogate.
Watch for
Nuclear transfer supplies the donor's nuclear DNA; the egg's cytoplasm still shapes early development.
