A Japanese has joined the elite club of humans whose genetic code has been fully sequenced, according to research unveiled on Sunday. The unnamed male gave a sample of DNA which has been unravelled to show all three billion base pairs, or "letters" in the double-helix code for life. Six other genomes are reported to have been fully sequenced since 2001.
They comprise the genomes of James Watson, who co-discovered the structure of DNA; Craig Venter, a US biotech tycoon; a male of the Yoruba ethnicity of western Africa; two Korean males; and a male of Han Chinese ethnicity. The study, published online in the specialist journal Nature Genetics, is headed by Tatsuhiko Tsunoda of the Centre for Genomic Medicine in Yokohama.
An international research consortium has launched the so-called "Thousand Genomes Project" aimed at fully sequencing the genomes of 1,000 anonymous individuals and placing the data in the public domain.
