(advantages and disadvantages)

On our planet, today everything is possible and humans made it that way. We have wide ranged opened sources and we apply those sources in our everyday life and we make something that helps us and whole planet. With making this we also sometimes make some problems with making even it will help us one of the examples of that is cloning which is really helping us but also it makes a huge trouble for people. Cloning is process of creating an organism which is exactly the same genetic copy of another organism used in process, that means that theirs DNA is the same. Today cloning developed in to two types and that is: reproductive cloning and therapeutic. Reproductive cloning is cloning of humans and therapeutic is cloning of cell from an adult. Most people think that cloning appeared in 20. century but it actually appeared in 1880s when biologist Hans Driesch first cloned a sea urchin, he took embryo and put it into beaker and than shacked it until cells separated. What is funny that Hans did not want to create identical organisms he just wanted to show that genetic material has no loss through cell division. Cloning was in science but who first accomplished it on animals was in 1950s with frogs and than in 1997 first mammal was cloned and that was sheep which died after six years, because this was success in a way people started to clone all other kinds of mammals. Today cloning is applied all over the world it is used to clone some organs from animals as food and also to clone human organs as a back-up organs, also it is used as an experiment on different kinds of animals. When it started to apply more and more people started to complain because most of people started to complain because most animals and other kinds of experimental creatures died, than people said that it is not our thing to do something which is not natural and that we...
