Jacob and Monod's work was important because they proposed the operon model which explains how genes are regulated in prokaryotic cells. They introduced the concept of gene regulation through the control of gene expression, shedding light on how genes are turned on or off in response to specific signals. This foundational research laid the groundwork for understanding how organisms regulate their genes to adapt to changing environments.

Who was the operon model of the regulation of gene expression in bacteria was proposed by?
The operon model of gene regulation in bacteria was proposed by François Jacob and Jacques Monod in 1961. They introduced the concept of operons, which are clusters of genes with related functions that are regulated together. This model has since become fundamental to our understanding of gene regulation in prokaryotic organisms.
Is there any reason rate of reaction would decrease with increased concentration?
Statistically this is a contradiction like: Is there a smaller chance of people meeting each other when there are LESS people at a meeting?? However some reaction kinetic models (e.g. Monod) explain that at increasing concentration of a reactant the rate doesn't increase (=it stays constant), the so called zero-order reaction-kinetic model (saturation-model)
