Laboratories have for the first time sequenced the full genetic code of an African and an Asian in what amounts to a major step towards the goal of a tailor-made profile of one's DNA.
Until now, the genomes of only two individuals - James Watson, who co-determined DNA's double-helix structure, and maverick biotech entrepreneur Craig Venter - have been unravelled.
Both men are of European descent, which leaves gaps in knowledge about how people of different ethnic backgrounds could be susceptible, or alternatively immune, to inherited diseases or respond to medicine.
Two studies, released on Wednesday by the British-based journal Nature, aim to fill in some of those blanks, with the genomes of a Han Chinese male and a man from the Yoruba ethnic group in West Africa.
The two teams describe the methods they used to expose the three billion base pairs of code in the anonymous individuals' DNA.
Later work, analysing the genomes of the four men, will compare and contrast changes in the code that could be linked to disease.
The two new genomes were compiled using...

James Watson, a scientist famous for ground-breaking work on DNA and notorious for expressing his antediluvian opinions, died on November 6, at the age of 97. Watson’s scientific eminence was primarily based on the 1953 discovery of the helical structure of DNA, for which he, Francis Crick and Maurice Wilkins shared the 1962 Nobel Prize in Physiology or...
