The Code Breaker traces the history of gene editing while simultaneously tracking Jennifer Doudna’s life — she has received a Nobel prize for being a pioneer of the CRISPR technology (an immune system that bacteria adapt whenever they get attacked by a new virus).
There is a key difference between this book and Isaacson’s biography of Steve Jobs. I did not learn anything new from the latter as I was aware of most of the key events in the life of Jobs and in the history of Apple; however the insights that he provided into Jobs’ personality and the behind-the-scenes happenings at Apple made it an extremely interesting read. The Code Breaker, on the other hand, was extremely informative given my limited knowledge of gene editing; however, in its quest for being informative, the book ends up being somewhat tedious.
Doudna has led an extremely laudable professional life. However, her personal life has been largely commonplace, and while Isaacson tries his hardest to create a sense of excitement around it, he fails to do so. He focuses all his efforts on this front in the third part of the book — Gene Editing — where he chronicles the intense rivalry between Feng Zhang and Doudna, tracing their race to get credit, important prizes and patents. But this attempt falls short.
The most interesting part of the book for me was the section where Isaacson explores the moral or ethical issues around gene-editing. This is best exemplified by the question, “would it be wrong to do so or would it be wrong not to do so”. Isaacson discusses where boundary lines should be drawn — somatic editing versus germline editing (the latter is hereditary), the use for treatment of diseases versus for enhancement of human characteristics, the types of diseases that should be edited out, disadvantages that are disabling versus those that are simply so because of societal constructs (such as homosexuality) and finally whether the individual or the community should control this. From this part onwards, the book is less about Doudna and more about the science.
The book ends on an optimistic note, while discussing the Covid-19 disease and the race to find a vaccine, on how reprogrammable RNA vaccines could pave a way for finding faster cures to diseases and pandemics in the future.
Pros: Helps understand the science of biogenetics, interesting debate on the ethical aspects
