Nobel in Chemistry Awarded for Directed Evolution of Enzymes and Antibodies

This year, the Nobel Prize in Chemistry recognizes that when scientists need to improve enzymes and antibodies, scientists sometimes find that the most rational thing they can do is abandon rational design. Instead, they may resort to directed evolution, that is, a human-directed version of the biology’s most powerful process.The pioneers of directed evolution recognized by the Nobel committee include Frances H. Arnold, Ph.D., the Linus Pauling Professor of chemical engineering, bioenginee
