Cloning Goes Artisanal in China
Meet Peng Peng, a clone whose cells have been engineered to contain a fatty-acid-producing gene (taken from a roundworm). Peng is the first transgenic sheep to be successfully produced by a "handmade" cloning technique.
The technique sounds, well, mysterious:
Du Yutao is one of the scientists who created Peng Peng in far Western China. She says handmade cloning is an emerging technique with great potential. It's less expensive than conventional cloning and can be performed in the field without the need for sophisticated equipment.
The Chinese government is encouraging of the project, perhaps because it has to feed 22 percent of the world's population and consumes a quarter of the world's industrially produced meat with limited resources. This year, China will put away 71 million tonnes of meat.
