A more thorough explanation:

DNA stands for deoxyribonucleic acid and is a molecule that contains genetic information. It is found in most living organisms and is responsible for determining traits such as eye color, height, and susceptibility to certain diseases.

DNA is unique to each individual, except for identical twins. This means that DNA testing can be used to determine parentage in a paternity suit or to identify a suspect in a criminal investigation.

For example, if a child is born and the father is unknown, a court might order a DNA test to determine who the biological father is. Similarly, if a crime is committed and DNA evidence is left behind, forensic scientists can use DNA testing to identify the perpetrator.

DNA testing has also been used to exonerate people who have been wrongfully convicted of crimes. In some cases, DNA evidence has been used to prove that someone else committed the crime or that the person was not at the scene of the crime at the time it was committed.
