Summary
Creating genetically identical animals through somatic cell nuclear transfer.
In depth
Dolly (1996) was the first mammal cloned from an adult cell. Uses: preserving livestock traits, endangered species, research. Issues: low success rates, welfare and shortened telomeres.
Somatic cell nuclear transfer reprogrammes a differentiated nucleus in the egg cytoplasm. Epigenetic errors lead to large offspring syndrome and early death. Mitochondrial DNA comes from the egg donor, so clones are not exact genetic copies.
Key idea: a clone shares nuclear DNA with the donor, but environment still shapes traits.
