Audio slideshow: 'The secret of life'

In 1953, two Cambridge University scientists published their answer to one of the most fundamental questions of biology - how do living things reproduce themselves? In their article for the journal, Nature, James D Watson and Francis Crick described the structure of a chemical called deoxyribonucleic acid, or DNA.

Now - six years after Crick's death - the Wellcome Library in central London is making many of his private research papers available on the web, including an early sketch of the DNA double helix.

The publication marks the start of an ambitious digitisation project by the library, to provide free, online access to millions of documents in its collection. Guided by the Head of the Wellcome Library, Simon Chaplin, take a look at some of the personal papers of Francis Crick - who, it is argued, made the most significant contribution to science to date.
