" For an enzyme to be functional, it must fold into a precise three-dimensional shape. How such a complex folding can take place remains a mystery. A small chain of 150 amino acids making up an enzyme has an extraordinary number of possible folding configurations: if it tested 1,012 different configurations every second, it would take about 1,026 years to find the right one. . . . Yet, a denatured enzyme can refold within fractions of a second and then precisely react in a chemical reaction. . . . [I]t demonstrates a stunning complexity and harmony in the universe.21 "
