There was a new professor that came to the lab, Professor Chibnall, who worked on proteins, and he brought a group with him, and he offered me a job, and the first job he offered me was to study insulin, which is the — you know, the substance that they give to diabetics, which was a fairly small protein, but they didn’t know anything about the actual chemical structure of it, except that it was built up of amino acids. And he and his group were mainly involved in the analysis of it, how many of the different amino acids were there. So, he gave me this job, and that’s really what put me on the ladder, really, because my expertise has all been in sequencing, sequencing of amino acids and proteins and, later on, nucleic acids, DNA.
