Answer» The correct option is (a) 1961 The EXPLANATION: The MECHANISM by which all the GENES of an operon operate, was first elucidated in 1961 by Francois Jacob and Jacques Monod of the Pasteur Institute in Paris. An operon consists of structural genes, a promoter REGION, an operator region and a regulator gene.
