Electrophoresis

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

DNA profiling (DNA fingerprinting) uses electrophoresis to compare crime scene samples with suspect DNA. Electrophoresis

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. An electrical current is applied

Uses narrow tubes instead of gels, allowing for high-speed separation and automation, commonly used in modern DNA sequencing. Real-World Applications allowing for high-speed separation and automation

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.
