The programme examined the rich symbolism of the double helix and also featured a sequence shot in the Wellcome Library with Prof du Sautoy examining our early sketch of the double helix from the papers of Francis Crick.
The episode is available for viewers in the UK through the BBC iPlayer, along with the rest of the series - including programmes on Da Vinci's Vitruvian Man and Florence Nightingale's 'Rose Diagram' - until 30th December.
