How
Cloning Works
Step 1— ENUCLEATION: The genetic material (DNA) of the recipient
human egg is removed through a process called enucleation.
Step 2 – SOMATIC CELL TRANSFER: A human
somatic cell of the donor (person to be cloned) is injected into the enucleated
egg. In this way, the recipient human egg now has the complete DNA of the
donor (person to be cloned).
Step 3 - CELL FUSION: An electrical pulse is applied across the two
cells causing them to fuse.
THE RESULT: An asexually reproduced HUMAN EMBRYO that is an identical
twin to the person seeking to be cloned.This is cloning as we know it today.
This process was used to
produce Dolly the sheep.
In Therapeutic Cloning, a cloned human embryo is used for spare partts
and is killed. In Reproductive Cloning, the cloned embryo is allowed
to be born.
