Analytical Brief - Cloning
Cloning is the process of creating copies of DNA, cells, or organisms, in other words, it is the “creation of an organism that is an exact copy of another” (What is Cloning?). An early embryo cell is separated in a petri dish and injected into a surrogate mother. Through cloning, scientists are able to make an exact genetic copy of a living organism. The clone and the original are identical in every way. Clones are able to function and interact with other living things, just as the original is able to. After news of cloning Dolly the Sheep in 1997, cloning has been a controversial topic.
Scientists use cloning to learn more about genes of different creatures and organisms. They are able to identify the purpose of each of the different genes and are able to better understand how cells work together in order for the organism to function properly. Clones help scientists learn about the different diseases that affect humans. At the moment, scientists have not cloned humans, but they have cloned animals. These clones can be used to for testing different remedies for the diseases, and scientists can observe how the cells and animal react. Because most of these “cures” and remedies for the diseases are based on trial and error, scientists are more comfortable testing on animals than humans because they are still unsure if the remedy will work or not. Because the clones are identical to the original animal, scientists do not have to worry about looking for animals with a certain trait or characteristic that is needed for the testing and trials.
Another use for cloning is for medicine. There are animals that can “produce drugs or proteins that are useful in medicine” and help humans with their illnesses (Why Clone?). Instead of waiting for animals to reproduce naturally, they can be cloned so that pharmacies will be able to make the drugs at a faster rate. This is extremely helpful when many people all over the world are...
