　　CCTV News (China News): shenzhen huada gene research institute announced today (11th) that the genome frame of the giant panda Jingjing has been drawn. This is another milestone contribution made by China scientists in the field of life science after completing the first yellow race genome map last year.

　　Why are giant pandas "dark circles"? Why don’t you hibernate as a "bear"? Why do you have a soft spot for "bamboo"? What will the giant panda look like in the future? Scientists’ interpretation of the giant panda "Jingjing" genome provides authoritative answers to these questions.

　　Studies have shown that the giant panda has 21 pairs of chromosomes, and the genome size is similar to that of human beings, about 3 billion base pairs, including 20,000-30,000 genes. Compared with the species that have been sequenced, it is also found that the genome of giant panda is the closest to that of dog in structure, and it is also similar to that of human beings, but quite different from that of mice in mammals.

　　It is understood that the study of giant panda genome can provide scientific basis and examples for the protection of endangered species, disease monitoring and artificial reproduction from the level of genomics. The most important thing is that this study fills the gap in international related research and provides the possibility for people to understand the giant panda more comprehensively at the genetic and molecular levels.

　　Wang Jun, executive vice president of shenzhen huada gene research institute, the project leader: The research level has really reached the scope of the whole genome, which comprehensively interprets the status quo of 30,000 genes in the whole panda. It can make people make a more comprehensive and extensive protection strategy for giant pandas.

　　On March 6th this year, scientists from five countries, including China, the United States and Canada, jointly put forward the "International Giant Panda Genome Project", aiming at jointly promoting research results and protecting endangered species. The genome sequence map of the giant panda Jingjing published on 11th is the first part. In the future, scientists in China will complete a detailed map of the giant panda genome within this year.
