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.

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

Uses narrow tubes instead of gels, allowing for high-speed separation and automation, commonly used in modern DNA sequencing. Real-World Applications Though the concept is simple—using electricity to push
