How cloning is used
Medical Purposes:
 * 1) Researchers learn about human diseases by genetically engineering mice to carry disease-causing mutations. Genetically engineering can be a time consuming process with trial and error but if they just clone the mice it will be quicker and more efficient.
 * 2) Researchers also use cloning stem cells for research. Since stem cells are the building blocks of the body they could possibly be used to repair damaged or diseased organs and tissue. They are looking for a way to genetically define and clone human stem cells for research and medical purposes.
 * 3) Today, farm animals like cows, sheep and goats to produce drugs or proteins that can be used in medicine. Cloning could be a potential way to produce large herds of genetically engineered animals.

Extinct Animals:
 * 1) Researchers are trying to create a way to bring dinosaurs back to life. This is very similar to what they do in Jurassic Park. They would use well preserved dino DNA to cone the animal but they must find a surrogate mother of a very similar species. They could potentially do this to other extinct animals to help bring them back to life.

Reproducing a Deceased Pet:
 * 1) Deceased animals could potentially be cloned with the preserved DNA and a lot of money. Currently, there is only 1 biotechnology company in the US cloning cats and they are now moving onto dogs. The animal cannot be expected to be the same because of the environmental factors they have had throughout their previous lives.

Cloning Humans:
 * 1) There is a large controversy over cloning humans for ethical, legal and social changes. The benefits for human cloning could potentially out way the faults. Researches predict that we will soon be able to genetically engineer infertile couples to have children. Also, if the DNA is saved from a deceased child, scientists could potentially bring them back to life.
