"Lively and entertaining... In [<em>The Catalyst</em>], the machinations of RNA emerge as a core feature of what makes us human. We appear to be at the beginning of a conceptual enlightenment in biology—an ‘age of RNA,’ as Mr. Cech calls it. Biology will never be the same."
- Adrian Woolfson - The Wall Street Journal,
"[An] impressively comprehensive work… [Cech] writes with easy charm and uses analogies helpfully and elegantly"
- The Times Literary Supplement,
"<em>The Catalyst </em>[is] a joy, from a writer who can't help but be as endearing as he is authoritative."
- Tom Leslie - New Scientist,
"RNA is arguably the most consequential molecule of them all. A Nobel-prize winning chemist explores its role in life’s origins as well as its medical uses."
- The Economist,
