Cloning
The idea of cloning is to make an identical copy of something. This process is completed by extracting the DNA from an adult animal cell and insert it into an egg cell. The embryo that is created is then zapped to start multiplying. This continues until the embryo becomes a blastocyst, which is a small clump of cells formed after an egg has been fertilized. In 1996, scientists Ian Wilmut and Keith Campbell cloned the first organism, which was Dolly the sheep. Dolly was the first animal to be cloned from an adult cell. Cloning should be allowed for animals, because it can prevent the animal species from becoming extinct. If animals were to be extinct, then we would not be able to study them ourselves, in modern day. If animals could reproduce, then our food supply would not run short any time soon. Cloning should also be allowed for humans, because it can help treat illnesses, such as replacing a kidney. Cloning should not be allowed for stem cell research, because they already have the capability of dividing

The potential benefits of cloning include medical reasons, reviving an endangered or extinct species or replacing a pet that is deceased. Cloning used in the medical field can allow us to have replicas of animals with certain diseases (Genetic Science Learning Center, 2014). If we allow cloning, we could reduce the amount of time needed to clone for a transgenic animal and spend more time on research. Cloning can revive an endangered or extinct species, and it can help us visualize different time periods in the past. Cloning pets before they are deceased can be a risky move, because you may not be getting the same pet that you knew before (Genetic Science Learning Center, 2014). Also, cloning humans can be a good idea, because there could be mental tragedies that occur to family
