Scientific research is one of the most exciting and rewarding of occupations.
It is like a voyage of discovery into unknown lands, seeking not for new territory but for new knowledge. It should appeal to those with a good sense of adventure.
Through art and science in their broadest senses it is possible to make a permanent contribution towards the improvement and enrichment of human life and it is these pursuits that we students are engaged in.
Science is not like the Olympic Games or something where there's a lot of people all trying to win gold medals, and if you don't get a gold medal, you're nothing. There are actually a lot of people working together and contributing to the science - and the science is the important thing.
When I was young my Father used to tell me that the two most worthwhile pursuits in life were the pursuit of truth and of beauty and I believe that Alfred Nobel must have felt much the same when he gave these prizes for literature and the sciences.
A DNA sequence for the genome of bacteriophage ΦX174 of approximately 5,375 nucleotides has been determined using the rapid and simple 'plus and minus' method. The sequence identifies many of the features responsible for the production of the proteins of the nine known genes of the organism, including initiation and termination sites for the proteins and RNAs. Two pairs of genes are coded by the same region of DNA using different reading frames.
I and my colleagues here have been engaged in the pursuit of knowledge.
After taking my B.A. degree in 1939 I remained at the University for a further year to take an advanced course in Biochemistry, and surprised myself and my teachers by obtaining a first class examination result.
And indeed this theme has been at the centre of all my research since 1943, both because of its intrinsic fascination and my conviction that a knowledge of sequences could contribute much to our understanding of living matter.
In this atmosphere I soon became interested in nucleic acids.
I was married to Margaret Joan Howe in 1940. Although not a scientist herself she has contributed more to my work than anyone else by providing a peaceful and happy home.
Influenced by him, and probably even more so by my brother Theodore a year older than me, I soon became interested in biology and developed a respect for the importance of science and the scientific method.
Initially I had intended to study medicine, but before going to University I had decided that I would be better suited to a career in which I could concentrate my activities and interests more on a single goal than appeared to be possible in my father's profession.
Until 1943 I received no stipend. I was able to support myself as my mother was the daughter of a relatively wealthy cotton manufacturer.
