From their own work and the work of others, he and Jacob came up with a model for how the levels of some proteins in a cell are controlled. In their model, the manufacture of proteins, such as the ones encoded within the lac lactose operon, is prevented when a repressor, encoded by a regulatory gene, binds to its operator, a specific site on the DNA next to the genes encoding the proteins.

It is now known that repressor bound to the operator physically blocks RNA polymerase from binding to the promoter, the site where transcription of the adjacent genes begins. Study of the control of expression of genes in the lac operon provided the first example of a transcriptional regulation system.

Monod is widely regarded as one of the founders of molecular biology. Monod's interest in the lac operon originated from his doctoral dissertation, for which he studied the growth of bacteria in culture media containing two sugars. Books by Jacques Monod.

At the present time we have no legitimate grounds for either asserting or denying that life got off to but a single start on earth, and that, as a consequence, before it appeared its chances of occurring were next to nil. Destiny is written concurrently with the event, not prior to it The universe was not pregnant with life nor the biosphere with man. Our number came up in the Monte Carlo game.

The biochemical processes that take place within an organism's cells are controlled by the genes found inside DNA molecules. Different cells work in different ways at different times, however. This too is regulated by genes.


Jacques Monod: Chance and Necessity

The basic tenet of this book is that systems in nature with molecular biology , such as enzymatic biofeedback loops, can be explained without having to invoke final causality. In this book, Monod adopted the term teleonomic to permit recognition of purpose in biology without appealing to a final cause. According to the introduction the book's title was inspired by a line attributed to Democritus , "Everything existing in the universe is the fruit of chance and necessity. The first U. Monod starts the preface of the book by saying that biology is both marginal and central. He goes on to explain that it is marginal because the living world is only a fraction of the universe.
