However, many people still do not fully understand cloning. This article describes what cloning is and what it means for people around the world. There are three types of cloning, DNA cloning, reproductive cloning and therapeutic cloning. DNA cloning had been conducted by scientists since the 1970s. It involves taking one part of a person‟s or an animal‟s DNA— a single gene— and placing it where it can reproduce itself many times on its own. This type of cloning has helped scientists produce body parts and ans in laboratories. Reproductive cloning is creating a person or an animal that is geically exactly the same as another. Therapeutic cloning uses human embryos for research and to develop cures for diseases. In many countries, the second two types of cloning are illegal. Dolly the sheep was the product of reproductive cloning. She gave birth to six baby sheep during her life, but by the age of six, she was seriously ill. She had cancer, and was put to sleep. Most sheep live for eleven or twelve years, but Dolly only lived for six years. While people worry about cloning leading to similarly early deaths in humans, people have many other worries as well. People worry that if we allow cloning, scientists will be able to create copies of people, which many people believe is not natural. People are also concerned about the effect on society, and worry that there will be many clones walking around everywhere. However, cloning does have benefits. DAN cloning can be used to build ans that can be given to people with failing ans who are waiting for transplants. Therapeutic cloning can be used to help disabled people walk again and to help cure diseases such as cancer. Many governments have made therapeutic cloning illegal, though, because it uses embryos for scientific research. Many people do not like the idea of creating new people and animals for science. 大家网高 考论坛 大家网，全球第一学习门户。 Despite the arguments against it, cloning can benefit people all over the world.
