From the Ted Talk by David Baker: 5 challenges we could solve by designing new proteins

Unscramble the Blue Letters

Proteins are lneiar chains of building blocks called amino acids. Nature uses an alphabet of 20 amino acids, some of which have names you may have heard of. In this prutice, for scale, each bump is an atom. Chemical forces between the amino acdis cause these long stringy molecules to fold up into unique, three-dimensional structures. The folding process, while it looks random, is in fact very precise. Each protein folds to its characteristic shape each time, and the folndig process takes just a fatiocrn of a second. And it's the shpaes of pnetoirs which enable them to carry out their remarkable biological functions. For example, hemoglobin has a shape in the lungs perfectly sietud for binding a molecule of oxygen. When hemoglobin moves to your muscle, the shape changes slightly and the oygexn comes out.

Original Text

Proteins are linear chains of building blocks called amino acids. Nature uses an alphabet of 20 amino acids, some of which have names you may have heard of. In this picture, for scale, each bump is an atom. Chemical forces between the amino acids cause these long stringy molecules to fold up into unique, three-dimensional structures. The folding process, while it looks random, is in fact very precise. Each protein folds to its characteristic shape each time, and the folding process takes just a fraction of a second. And it's the shapes of proteins which enable them to carry out their remarkable biological functions. For example, hemoglobin has a shape in the lungs perfectly suited for binding a molecule of oxygen. When hemoglobin moves to your muscle, the shape changes slightly and the oxygen comes out.
