Electrophoresis ★ Real

Molecules are loaded into a porous gel, typically made of agarose (for large DNA fragments) or polyacrylamide (for smaller DNA or proteins). This gel acts as a molecular sieve.

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.

Researchers use it to isolate specific genes for cloning or to study mutations. Conclusion Molecules are loaded into a porous gel, typically
