Perhaps the most dangerous ethical leap made by
OAR proponents is that science, by itself, can answer the critical ethical question: Does the zygote exist, for even a short time, during the OAR procedure?
If these experiments support their hypothesis, they will be able to go on to similar human - cloning experiments because, according to
OAR proponents, there is no moral issue left to be determined.
OAR proponents claim that when the altered donor - cell nucleus with its activated nanog gene is transferred to the enucleated oocyte (egg cell), the presence of nanog will immediately convert the enucleated egg cell to a pluripotent cell, without ever forming a zygote.
