DNA fingerprinting is a chemical test that shows the genetic makeup of a person or other living things. It’s used as evidence in courts, to identify bodies, track down bloodrelatives, and to look for cures for disease.
Your Genetic Map
DNA is short for deoxyribonucleic acid, which is inside of every cell in your body. It’s a chain of chemical compounds that join together to form permanent blueprints for life.
These compounds are called bases, and there are 4 of them. They pair up with another to form what are called base pairs. Your DNA has about 3 billion of these couples. The way they’re strung together tells your cells how to make copies of each other.
The complete set of your compounds is known as a genome. More than 99.9 % of everyone’s genome is exactly alike (100% if you are identical twins). But the tiny bit that’s not is what makes you physically and mentally different from someone else.
DNA fingerprinting uses chemicals to separate strands of DNA and reveal the unique parts of your genome. The results show up as a pattern of stripes that can be matched against other samples.
Uses
Since it was invented in 1984, DNA fingerprinting most often has been used in court cases and legal matters. It can:
Physically connect a piece of evidence to a person or rule out someone as a suspect.Show who your parents, siblings, and other relatives may be.Identify a dead body that’s too old or damaged to be recognizable.
DNA fingerprinting is extremely accurate. Most countries now keep DNA records on file in much the same way police keep copies of actual fingerprints.
It also has medical uses. It can:
Match tissues of organ donors with those of people who need transplants.Identify diseases that are passed down through your family.Help find cures for those diseases, called hereditary conditions.
