Nobel Prize-winning American scientist James Watson has died aged 97.
His scientific research and discoveries opened the doors to help explain how DNA replicates and carries genetic information, setting the stage for rapid advances in molecular biology.
His honorary titles were stripped in 2019 after he repeated comments about race and intelligence. In a TV programme, he made a reference to a view that genes cause a difference on average between blacks and whites on IQ tests.
The death of Watson, who co-discovered the double-helix structure of DNA in 1953, was confirmed to the BBC by Cold Spring Harbor Laboratory, where he worked and researched for decades.
