Discovery of introns.

In 1993 Roberts shared the Nobel Prize in Physiology or Medicine with Phillip A. Sharp  "for their discoveries of split genes." It was frequently suggested that Chow deserved a share of that prize. The normally inappropriate word "amazing" in the title of this paper was allowed in this particular instance by the editors of the journal Cell because of the exceptional nature of the discovery. Order of authorship in the original paper: Chow, Gelinas, Broker, Roberts.
