Cloning: The Ups and Downs

• Methods of Cloning
-There are many possible ways to clone an organism, but two successful examples are:
• Dolly’s case
-Dolly was cloned by Ian Wilmut
-Wilmut fused an udder cell from a six year old sheep with the egg cell from another sheep after removing the genetic material from the egg
• The mice
-In Hawaii a student named Teruhiko Wakayama cloned mice
-Mice were thought to be the worst candidate for cloning because their egg cells are very delicate and their embryos developed rapidly
-Wakayama used adult, or differentiated cells
-Differentiated cells are cells that have already become specialized
-He took the nucleus out of the adult cell and injected it into an empty egg
-Wakayama produced three generations of identical mice, 50 in all
• Medical Uses
-Cloning can be used in the medical field in many ways
•Cloning can be used to eliminate donor rejection
-If the body’s immune system senses something fore...
