The Discovery of the lac Operon. In 1961, Francois Jacob and Jacques Monod proposed the operon model of gene regulation in bacteria. The model was based on their study of the genes in E. coli that code for enzymes that affect the breakdown of lactose. Francois Jacob and Jacques Monod. Photo courtesy of Archive Photo. Because of the pioneering work of Jacob and Monod, the lac operon is typically used to illustrate gene regulation in bacteria.
To understand cis gene and before going ahead let us first learn what is operon (best example of cis-gene) ? An operon is a functioning unit of genomic DNA. This contains a cluster of genes which have a single point control.That single point control is called as regulatory signal or promoter.Lac Operon is the best example of Cis-gene.hese genes are adjacent to each other (hint: means on same part of its own DNA-Cis gene) and has single point control (so called as operon) These are called as lacZ, lac Y and lac A respectively & together constitutes lac operon (Cis-gene).
