Research scientists are working to develop the technology to clone humans, which would involve extracting DNA from a cell and implanting it into another cell of the same species. This process is very expensive and inaccurate, as shown by the 276 attempts needed to produce Dolly the sheep. Supporters argue that cloning could be used to preserve endangered species or create organs for transplants, but it also raises ethical concerns about the welfare of cloned animals and humans.

2. Research Scientists use expensive advances in technology to try to discover the correct process to clone a human.

3. Testing Scientists have already cloned many organisms by extracting DNA from a cell and implanting the DNA into another cell of the same species. This process costs a great amount of money and is not very accurate.

4. Cloned Animals However, sometimes scientists can clone many farm animals including this sheep named Dolly. But even a sheep took 276 tries to create!

6. Jurassic Park starts out as a park to educate others on how the dinosaur once lived in its natural habitat. It was designed as a tourist attraction and a way of preserving a species.

7. But after some lone person had an evil idea, the park turned into dungeon for the humans that were trapped inside.

8. Also, the same plot was used in the Star Wars saga: Attack of the Clones. An army of clones were used to protect the Republic from the clutches of the Sith.

9. Then, the clones were tapered with and the Sith gained control over the massive army of clones. These clones then destroy the advances of the Republic.
