In 1960 Khorana accepted a position as co-director of the Institute for Enzyme research at the Institute for Enzyme Research at the University of Wisconsin at Madison. He became a professor of biochemistry in 1962 and was named Conrad A. Elvehjem Professor of Life Sciences at Wisconsin–Madison. While at Wisconsin, "he helped decipher the mechanisms by which RNA codes for the synthesis of proteins" and "began to work on synthesizing functional genes" according to the American Chemical Society. During his tenure at this University, he completed the work that led to sharing the Nobel prize. The Nobel web site states that it was "for their interpretation of the genetic code and its function in protein synthesis". Har Gobind Khorana's role is stated as follows: he "made important contributions to this field by building different RNA chains with the help of enzymes. Using these enzymes, he was able to produce proteins. The amino acid sequences of these proteins then solved the rest of the puzzle."
