Fred Sanger on Conducting an Experiment with Sydney Brenner
  Fred Sanger     Biography    
Recorded: 16 Jun 2005

We were trying to identify a change in a mutant really, in a bacteriophage. In a bacteriophage he had there was a mutant and there was a change. We wanted to find out what the change was. So I had sort of techniques for spotting the sequences in this. It turned out there wasn’t a mutant. He had gotten the wrong phage. But it was fun. You know, he sort of taught me a few techniques and things. His approach is very different from ours.

Frederick Sanger, OM, CH, CBE, FRS (born 13 August 1918) is an English biochemist and twice a Nobel laureate in chemistry. In 1958 he was awarded a Nobel prize in chemistry "for his work on the structure of proteins, especially that of insulin". In 1980, Walter Gilbert and Sanger shared half of the chemistry prize "for their contributions concerning the determination of base sequences in nucleic acids". The other half was awarded to Paul Berg "for his fundamental studies of the biochemistry of nucleic acids, with particular regard to recombinant-DNA".

He is the fourth (and only living) person to have been awarded two Nobel Prizes, either wholly or in part.
