Nobel Prize-winning American scientist James Watson, one of the co-discoverers of the structure of DNA, has died aged 97.
In one of the greatest breakthroughs of the 20th century, he identified the double-helix structure of DNA in 1953 alongside a British scientist, Francis Crick, setting the stage for rapid advances in molecular biology.
But his reputation and standing were badly hurt by his comments on race and sex. In a TV programme, he made claims about genes causing a difference in average IQ between blacks and whites.
The death of Watson was confirmed to the BBC by Cold Spring Harbor Laboratory, where he worked and researched for decades.
