9、esperately trying to clone the animal and save the endangered species many years ago, with only about 1, 000 pandas left in the world.

10、aimed at collecting eggs, embryos（胚胎）, semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & Ms College of Veterinary Medicine, said there would be enough of the basic building blocks to reintrod
11、uce the species in the future. It was estimated that as many as 2, 000 species of mammals, birds reptiles would become extinct in over 100 years. The panda, native only to China, was in danger of becoming extinct in the next 25 years. This week, Chinese scientists said they grew an embryo by introdu
12、cing cells from a dead female panda into the egg cells of a Japanese white rabbit. They were then trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete. “The nucleus transfer（核子移植）of one species to another is not easy, and the lack of a
13、vailable（capable of being used）panda eggs could be a major problem,” Kraemer believed. “They will probably have to do several hundred transfers to result in one pregnancy （having a baby）.
