Reiji Okazaki was a pioneer Japanese molecular biologist, known for his research on DNA replication and especially for describing the role of Okazaki fragments along with his wife Tsuneko.
Okazaki Fragments
In 1968, Reiji and Tsuneko Okazaki discovered the way in which the lagging strand of DNA is replicated via fragments, now called Okazaki fragments. Their experiments used E. coli. After introducing 3T-thymidine for only ten seconds to E. coli during DNA replication, they placed the sample in a test tube of alkaline sucrose. ==References==
