|Biological systems are made of basic building blocks such as amino acids. These building blocks self-assemble into bigger units. The units then stack up to make larger organization. At the level of physics, shapes and charges play important roles in this assembly process. This simulation demonstrates their effects. Note that the animation below shows when the charges are removed, the pentagonal structure falls apart, and when they are added back on, it will re-assemble.|
