DNA is divided into smaller bits in the lab using restriction enzymes (also known as restriction endonucleases).
[Editor's note: Gel electrophoresis is used in DNA fingerprinting to identify between genetic material samples.Enzymes are used to break down the human DNA molecules into a collection of smaller, more manageable bits at specific characteristic places.
When an electric current is supplied, a process called gel electrophoresis separates particles according to their charge and size across a gel.DNA, amino acids, peptides, and other molecules can all be charged particles.a technique that makes use of an electrical field to separate DNA from a gelatin-like substance.
