- The first mammal to have been successfully cloned from an adult cell
- Cloned at the Roslin Institute in Scotland in 1996, where she lived until her death when she was six
- Significance: Proved that genetic material from a specialized adult cell could be used to create an entire new organism,
not just the one it was specialized for
- Scientists had previously thought that once a cell became specialized for a certain organ or other type of cell, the change
was permeneant and other uneeded geanes would become inactive
- This lead many to beleive that the errors or incompleteness in the reprogramming process cause the high rates of death,
deformity, and disability observed among animal clones
- The odds:
- 277 eggs were used
- 29 embryos were created
- 3 lambs produced at birth
- 1 lived
