Frederick Sanger, the British biochemist who twice won the Nobel Prize has died at the age of 95.
He is considered the ‘father of genomics’ after pioneering methods to work out the exact sequence of the building blocks of DNA.
Dr Sanger also developed techniques to determine the chemical structure of proteins including the hormone insulin.
He worked until he was 65 when he retired to spend more time “messing about in boats”.
