  凯发k8娱乐网址Zhong Zhong, the world's first cloned monkey, had its first birthday on Tuesday.   世界首只体细胞克隆猴“中中”周二一周岁了。
    The healthy primate1 is living with another cloned monkey named Hua Hua at the Chinese Academy of Sciences' Institute of Neuroscience in the city of Suzhou, according to Shanghai Observer.   Zhong Zhong and Hua Hua are clones created by scientists at the institute using somatic cell nuclear transfer, which was the same technique used to create the world's first cloned animal, Dolly the Sheep.   "The purpose of cloning monkeys is to produce animal models that are helpful for medical research and human health", said Sun Qiang, the director of nonhuman primate research at the institute.   One of the next major milestones2 in the research will come in three to four years time, when scientists will learn if the pair have the ability to reproduce.   Authorities in China have said they have no plans to allow human cloning following the success of the monkey experiments.
