Electrophoresis Official

Used for proteins. The detergent SDS unfolds the proteins and gives them a uniform negative charge, ensuring they are separated strictly by length rather than shape.

An electrical current is applied. Since DNA and RNA are negatively charged due to their phosphate backbone, they migrate toward the positive electrode (anode). Electrophoresis

Though the concept is simple—using electricity to push molecules through a "filter"—electrophoresis is one of the most powerful techniques in modern science. It transformed biology from a descriptive field into a precise, molecular discipline, providing the visual evidence needed to map the human genome and solve complex medical mysteries.
