Protein
From Eterna Wiki
Proteins are the molecular machines that control just about every process in the body, from replicating DNA to fighting infection. They are, in a way, nature’s robots. Just as a robot must be precisely constructed to do its job so too a protein must adopt a precise structure to work correctly. The staggering thing is that a protein molecule has more possible structures available to it than there are atoms in the universe. Nevertheless, when a protein molecule is made it folds up into its correct structure in fractions of a second. This is sort of like throwing all the pieces of a car in the air and expecting them to form a fully functioning machine upon landing. (Dr Marc Lorch)
