5. 1st Step: Isolate
donor cells
2nd Step:
enucleation
3rd Step: fusion of
both cells
4th Step: cell division
stimulation5th Step: embryo transfer
into a foster mother
6th Step: deliver a new
baby clone

6. Isolate
donor cells
Remove
and discard
the nucleus
from the
egg cell
Transfer the
somatic egg
nucleus into
the
enucleated
egg cell
Stimulate
cell division
Implant the
embryo into
the
“surrogate
mother”
Deliver the
baby
