In the presence of lactose, some of the lactose is converted to allolactose, which binds to the repressor making it no longer able to bind to DNA, and the transcriptional repression is lifted. In addition to his research activities, Jacob wrote important books on the history and philosophy of the life sciences, including La Logique du vivant: une histoire de l’hérédité (1970; The Logic of Life: A History of Heredity). [12] Jacob remarried in 1999 to Geneviève Barrier.[13].

After attending the Lycée Carnot in Paris, he began studying medicine at the Faculty of Paris, with the intention of becoming a surgeon. Biographie : François Jacob est un chercheur en biologie français. Jacob and Monod made key experimental and theoretical discoveries that demonstrated that in the case of the lactose system outlined above (in the bacterium E. coli), there are specific proteins that are devoted to repressing the transcription of the DNA to its product (RNA, which in turn is decoded into protein). In this way, a robust feedback loop is constructed that allows the set of lactose-digesting proteins products to be made only when they are needed. [11], Also in this period, he met and began courting his future wife, Lise Bloch.

Francois Jacob is credited as Biologist, Operon theory of genetic control, Nobel laureate. Blessé grièvement en Normandie, en août 1944, il ne pourra exercer sa spécialité et s'orientera vers la biologie. Enzyme levels in all cells is regulated by feedback on transcription.. Like his colleague Monod, Jacob was an almost lifelong atheist. They also found that in a normal cell the balance between regulator and structural genes enables the cell to adapt to varying conditions. Instead, after observing a surgical operation that cemented his "slight interest" in medicine, he entered medical school.[8]. He was famous for being a French biologist.

François Jacob (17 June 1920 – 19 April 2013) was a French biologist who, together with Jacques Monod, originated the idea that control of enzyme levels in all cells occurs through regulation of transcription. For instance, if a bacterium finds itself in a broth containing lactose, rather than the simpler sugar glucose, it must adapt itself to the need to 1) import lactose, 2) cleave lactose to its constituents glucose and galactose, and 3) convert the galactose to glucose. In 1961 Jacob and Monod explored the idea that the control of enzyme expression levels in cells is a result of regulation of transcription of DNA sequences. Jacob served in North Africa and participated in the invasion of Normandy in 1944.

With a coworker at the Pasteur Institute, Jacob discovered that the genes of a bacterium are arranged linearly in a ring and that the ring can be broken at almost any point. Though attracted to research as a career, he was discouraged by his own perceived ignorance after attending a microbiology congress that summer. Cursó estudios en la Facultad de Medicina de París, donde perteneció a un grupo de brillantes alumnos del biólogo André Lwoff.

He wanted a sibling and thought his parents unjustly denied him the accomplice and playmate he was entitled to. For many years it had been known that bacterial and other cells could respond to external conditions by regulating levels of their key metabolic enzymes, and/or the activity of these enzymes. Jacob, who had only completed his second year of medical studies, joined the medical company of the French 2nd Armored Division in 1940. Albert Franck, Jacob's maternal grandfather, a four-star general, was Jacob's childhood role model. In 1958 Monod and Jacob began to collaborate on studies of the regulation of bacterial enzyme synthesis. Current researchers find regulatory events at every conceivable level of the processes that express genetic information.

JACOB, FRANÇOIS (1920–), French molecular biologist and Nobel laureate. An inquisitive child, he learned to read at a young age. While partnering with Jacques Monod, they came up with the notion that enzyme control in all cells is achieved through effective regulation of transcription. One of their first major contributions was the discovery of regulator genes (operons), so called because they control the activities of structural genes. During the German occupation of France—and on the heels of his mother's death—Jacob left France for Great Britain to join the war effort. Most of the work of Jacob, Lwoff, and Monod was carried out at the Pasteur Institute (Paris), which Jacob joined in 1950 as a research assistant. This repressor (the lac repressor) is made in all cells, binding directly to DNA at the genes it controls, and physically preventing the transcription apparatus from gaining access to the DNA. Instead he took a position at the Cabanel Center, where he had done his thesis research; his new work entailed the manufacture of antibiotic, tyrothricin.

In the relatively simple genome of baker's yeast, (Saccharomyces cerevisiae), 405 of its 6,419 protein-encoding genes are directly involved in transcriptional control, compared to 1,938 that are enzymes.
