François Jacob

François Jacob was a French biologist who significantly advanced our understanding of genetics and molecular biology. He is best known for his work on the regulation of gene expression, particularly through the discovery of the operon model, which explains how genes can be turned on or off in response to environmental changes. Jacob's research paved the way for modern genetics, impacting fields like medical biophysics by enhancing our understanding of how genes control cellular functions and how this knowledge can be applied to medicine, such as in genetic therapies and understanding diseases at a molecular level.
