Uses somatic cell nuclear transfer, or SCNT, to transfer genetic material from the nucleus of a donor adult cell to an
egg whose nucleus, and thus its genetic material, has been removed
Once the embryo reaches the proper stage, it is transferred to a female host, where it will remain until birth
The catch: Clones are not exactly identical to the donor animal
- Only the clone's chromosomal or nuclear DNA is the same as the donor
- Somatic cells may contain mutations in their DNA
- Some genetic material comes from the mitochondria of the enucleated egg. Acquired mutations from the mitochondria's own
short segments of DNA are believed to play an important role in the aging process.
