Jacob, François (1920–2013)

Francois Jacob

François Jacob was a French biologist who, with Jacques Monod, discovered that a substance, which they named messenger RNA (mRNA), carried hereditary information from the cell nucleus to the sites of protein synthesis and that certain genes, called operator genes, control the activity of others. They shared the 1965 Noble Prize in Physiology or Medicine with another French biologist, André Lwoff.
