凭借在开发基因组编辑方法方面做出的贡献，詹妮弗·杜德纳和埃马纽埃尔·卡彭蒂耶成为2020 年诺贝尔化学奖获得者。 而詹妮弗·杜德纳对基因科学的痴迷最早始于其在六年级时读到的一本书——《双螺旋》。

When Jennifer Doudna was in sixth grade, she came home one day to find that her dad had left a book titled The Double Helix on her bed. She put it aside, thinking it was one of those detective tales she loved.

On a rainy Saturday, she picked up the book. As she sped through the pages, she became fascinated by the drama, which encouraged her to explore nature's wonders. Even though her high school teacher told her that girls didn't become scientists, she decided she would.

She worked with a biologist, Charpentier, to turn a curiosity about nature into an invention—an easy-to-use tool that can edit DNA. Known as CRISPR, the tool will transform the human race. James Watson, the author of The Double Helix, later told her it was the most important biological advance since he and Francis Crick discovered the structure of DNA.

For this achievement, Doudna and Charpentier were awarded the Nobel Prize in Chemistry in 2020. So far, only 7 women, beginning with Marie Curie in 1911, have won or shared the Nobel Prize in Chemistry out of 185 award winners. When the year's prize was announced,Dr. Charpentier said it would provide a message specifically for young girls who would like to follow the path of science and to show them that women can also be awarded prizes.

A few decades from now, if it becomes possible to edit DNA, should we allow parents to improve the IQ and physical strength of their kids? Should we let them decide eye color? Skin color? Height? After helping to discover CRISPR, Dr. Doudna has become a leader in considering these moral issues. That's the main message we should take from this Nobel: New technologies can be a huge benefit to the human race, but in order to make sure they are used wisely, it's important for people to understand them.
