In the movie Jurassic Park，scientists clone dinosaurs by
using the DNA that was preserved for millions of years．However，there is trouble when the cloned dinosaurs turn out fiercer and smarter than expected．Can dinosaurs really be cloned？ Theoretically，they can； all that would be required is DNA from an extinct dinosaur and a currently living closely related species which would act as a surrogate mother(代孕母亲)．In fact，there is continuing research to clone the Woolly Mammoth by extracting (提取) the DNA from frozen animals．

主题导读
Two commonly discussed types of theoretical human cloning are: therapeutic cloning(治疗性克隆) and reproductive cloning(生殖性克 隆).Therapeutic cloning would involve cloning cells from a human for use in medicine and transplant,and is an active area of research,but is not in medical practice anywhere in the world.Two common methods of therapeutic cloning that are being researched are somatic cell nuclear transfer(体细胞核移植) and,more recently,pluripotent stem cell(多能干细胞) induction.Reproductive cloning would involve making an entire cloned human,instead of just specific cells or tissue.

With the cloning of a sheep known as Dolly in 1996 by somatic cell nuclear transfer (SCNT),the idea of human cloning became a hot debate topic.Many nations outlawed it,while a few scientists promised to make a clone within the next few years.The first hybrid human clone was created in November 1998,by Advanced Cell Technology.It was created by using SCNT—a nucleus was taken from a man’s leg cell and inserted into a cow’s egg from which the nucleus had been removed,and the hybrid cell was cultured,and developed into an embryo.The embryo was destroyed after 12 days.
