Walter Isaacson talks about the life of Nobel laureate Jennifer Dowdna, a scientist who discovered a way to edit the genome. The author begins with the heroine's childhood in Hawaii and tells how she was inspired by James Watson's book "The Double Helix", an autobiographical work about the discovery of the structure of DNA, at the age of 12. Daudna became a promising young scientist and was able to achieve outstanding success in her field, becoming one of the leading experts in the field of genetic research. Isaacson details how she collaborated with other scientists to make the breakthrough that led to the discovery of CRISPR, a system that allows genome editing.However, this book is not only a biography of Daudna, but also a history of the development of the science of genetics. Along with an accessible explanation of what exactly Daudna and her colleagues discovered and developed, this book also examines the less discussed aspects of modern science: the struggle for funding, the contradictions between the goals of academic research (scientific progress) and the interests of the private sector (profit), the difficult process of publishing and patenting discoveries, as well as the confrontation between scientists.
