Tsuneko and Reiji Okazaki's early research consisted of studying DNA synthesis and specific nucleotide characteristics in frog eggs and sea urchins. This work led to the discovery of thymidine-diphosphate rhamnose, a sugar linked nucleotide, which then opened up the doors for them to work in the U.S.
