Today we took a stroll along the national cycle route 11 between Cambridge and Great Shelford. It's about a mile or more and the main attraction is that it also has colour coded stripes of the 10,257 base that form one side of a BRCA2 gene.
This celebrates the work done in the Sanger Institute nearby and the 10,000th mile of the National Cycle Network.
There are only four bases in DNA strands. it's amazing how much complexity it can encode.
