English homework 1.Background Hello, my name is Yuki Sakamoto, and today I'd like to talk about Ian Wilmut and his work to create a clone of sheep. The cloning technology using the fertilized egg nuclei has already completed before. So, more than 150 cloned cattle are made by using this technology in Japan. In contract, it is very difficult to create cloned animals of mammals using somatic nuclei. It is because, in the growing animal, the nature of cell has solidified for each tissue and organ. If he can make this technology, people can create a lot of clones. Moreover, it is genetically the exact same copy as the original animal. Once this technology is completed, it is the realization of dream biotechnology that can mass produce excellent cows and sheep, and can save wild animals that were extinct. 2.Research question Can people make a clone of sheep by using somatic nuclei? 3.Methods and data He pulled out the nucleus containing the DNA from the sheep's cell of six years old. And transplanted to other sheep's egg cells. When this was transferred to the third sheep, a sheep with the exact same gene as the original sheep was born. The sheep was named Dolly. 4.Conclusion They could make clone of sheep. This allowed people to get skills to make complete clones of mammals. So if want, we can make human clones.
