Can we cure genetic diseases by rewriting DNA? | David R. Liu

In a story of scientific discovery, chemical biologist David R. Liu shares a breakthrough: his lab's development of base editors that can rewrite DNA.

Learn more about how these molecular machines work -- and their potential to treat or even cure genetic diseases.
