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.
The process relies on the principle that many biological molecules possess an electrical charge. When placed in an electric field, these molecules migrate toward the electrode with the opposite charge. Electrophoresis
The standard method for separating DNA fragments, often used after a PCR (Polymerase Chain Reaction) to verify results. Molecules are loaded into a porous gel, typically
Electrophoresis is the backbone of several critical scientific fields: Electrophoresis
DNA profiling (DNA fingerprinting) uses electrophoresis to compare crime scene samples with suspect DNA.
