Mario Capecchi (Nobel laureate)

Mario Capecchi is a molecular biologist who won the Nobel Prize in Physiology or Medicine in 2007 for developing a method to create specific gene modifications in mice. This technique, called gene targeting, allows scientists to study the functions of individual genes by "knocking out" or altering them. His work has significantly advanced our understanding of genetics and disease processes, paving the way for medical research and potential therapies. Capecchi's innovations have provided powerful tools for understanding biology at the molecular level, especially in studying human diseases through animal models.
