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.

In this atmosphere I soon became interested in nucleic acids.

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.

Scientific research is one of the most exciting and rewarding of occupations.

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.

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.

Until 1943 I received no stipend. I was able to support myself as my mother was the daughter of a relatively wealthy cotton manufacturer.
