Borrowing from the humanities, Robert Pollack offers an entirely fresh perspective: DNA, he argues, should be seen as a great work of natural literature, a three-billion-year-old, continuously evolving text.
An award-winning scientist and teacher, Pollack displays both a sophisticated understanding of biology and a remarkable gift for metaphor. In elegant prose, he shows precisely how DNA provides the instruction book for life. He takes us deep inside a living cell—a teeming walled city—and explains how the genetic script at its heart governs all its operations. He opens the book containing the human genome and lucidly reveals the process by which biologists and physicians have begun to read its words and sentences. But the frontier of genetics now extends into troubling territory. Pollack identifies…
