Everyone has heard of DNA. But by itself, DNA is just an inert blueprint for life. It is the ribosome—an enormous molecular machine made up of a million atoms—that makes DNA come to life, turning our genetic code into proteins and therefore into us. This book is an insider account of the race for the ribosome’s structure, a fundamental discovery that both advances our knowledge of all life and could lead to the development of better antibiotics against life-threatening diseases. But this is also a human story of Ramakrishnan’s unlikely journey, from his first fumbling lab experiments to his fierce competition with some of the world’s best scientists.
