Upon electrical stimulation, smaller fragments of a molecule will move faster through the gel than larger fragments. The process is typically done to separate DNA fragments after the DNA has been cut with restriction enzymes.

Gel electrophoresis
The process of separating charged species by subjecting them to a voltage gradient. A gel (made of agarose or polyacrylamide) provides mechanical support and prevents mixing of the molecules being separated.

Thermal gel gradient electrophoresis (TGGE)
A method for separating DNA fragments according to their mobilities under increasingly heat-denaturing conditions. See also DGGE, SSCP and heteroduplex analysis.
