Here starts the DNA path. Each end of the path is marked by a sculpture of the DNA double helix magnified 750,000,000 times. In 2005, as a celebration of the 10,000th mile of the national cycle network, Cambridgeshire County Council and Sustrans joined forces with the Wellcome Trust Sanger Institute to create a DNA-inspired cycle path. The path, which runs from Addenbrooke's Hospital to Great Shelford, is decorated with 10,257 colourful stripes which represent the four nucleotides of the BRCA2 gene. BRCA2 (Breast Cancer Type 2 susceptibility protein) was discovered at the Sanger Institute by Prof. Michael Stratton and Dr Richard Wooster in 1995.
