I was trained with somebody called Fred Sanger, who won a Nobel Prize, first for sequencing proteins, and he was working on the sequencing of nucleic acids, DNA and RNA, but then DNA when I was a Ph.D. student with him. And so there was very few ways of sequencing DNA then, and one of the things you could do was sequence DNA at the very ends of the long DNA molecules that make up genomes, and so I saw that there would be a feasibility, a way of looking at the ends of DNA, whereas perhaps in those days you couldn’t look at the middle of DNA so well. And I went to Joe Gall’s lab, and was interested in pursuing this, and Joe Gall, who I mentioned before was a really good mentor, is also an extremely good biologist in recognizing there are good biological systems for asking certain questions. And he was the one who said, “There is this system that has very small short chromosomes,” and lots of them, meaning lots of ends, so that this would be something that — you know, this would be a system. And I was excited because I wanted to look at the ends of things, the ends of DNA, which nobody really had been able to look at in eukaryotes, organisms like us that had nuclei in their cells. And so it was partly that it was doable, and partly because there was a good system to do it in.
