Har Gobind Khorana, 89, MIT biochemist and Nobel laureate
the 1968 Nobel Prize in Physiology or Medicine for helping decipher the genetic code and later went on to synthesize the first artificial gene, died Wednesday at a rehabilitation facility in Concord after a brief illness. He was 89. Dr. Khorana was the Alfred P. Sloan professor of biology and chemistry, emeritus, at MIT. As the dual affiliation indicates, his work eluded easy categorization, drawing on chemistry, biochemistry, molecular biology, and biophysics.
