Video: How are we so good at folding proteins?
Key Points
Proteins carry out almost every important function in our body, from copying our DNA to turning the food we eat into energy. These tiny "molecular machines" are first made by our cells as straight chains, like long pieces of string. Then, to work properly, each protein must fold into an intricate 3D shape.
