CLONING ANIMALS

HOW ARE ANIMALS CLONED?

• Researchers take a cell from the animal they wish to clone
• The donor egg's nucleus is removed and the new DNA is inserted
• An electrical current is used to fuse the cell
• The egg develops somewhat over time
• Egg is put into another animal who carries the fetus clone

PROS AND CONS

PROS

• Same features as animal cloned from
• Faster reproduction in groups
• Helps researchers
• Source for possible needed organs

CONS

• Expensive
• Meats and food products not yet tested
• Unfavorable
• Arguments against

An interesting fact I learned was that animal cloning is being used for food products, possible needed organs and for faster reproductions for herds and flocks of animals.

The sheep in the background was Dolly the sheep, the first ever cloned animal.
