Some Parallels Between Gene Control Systems in Maize and in Bacteria
In this article, McClintock attempted to link the regulation of controlling elements to observations made by Francois Jacob,
 Jacques Monod, and Andre Lwoff on bacterial operons in 1960. In part, McClintock was trying to establish her preeminence
 in the study of gene regulation, but she also wanted to demonstrate that regulation was widespread among organisms. Many of
 the parallels she observed were not universally accepted and McClintock backed off most of her claims by 1968.
