The DNA sequence of human insulin was first chemically synthesized by Keiichi Itakura (often written as Hakura in some sources) and Arthur Riggs in 1978. They chemically synthesized the genes for the A and B chains of insulin separately and inserted them into plasmids to produce insulin in bacteria.

Sir Edward Sharpey Schafer coined the term 'insulin'.

Gilbert and Villa-Komaroff were involved in the synthesis of rat insulin using recombinant DNA technology.

Dr. Har Gobind Khorana is credited with synthesizing the first artificial gene (yeast alanine tRNA).

Answer: Hakura.
