DNA testing has exploded in the scientific, medical, and judicial world over the past few years as a sure-fire way to find out one’s identity. This type of testing answers questions regarding one’s lineage, who committed crimes, as well as thousands of other scientific advances that come from these small strands of genetic makeup. Almost every cell found within the human body contains DNA and other living organisms also contain DNA. The thing that makes DNA so unique, and so helpful, is that no two people, with the exception of identical twins, have the exact same DNA. Siblings, parents, and children may all have similar DNA but they will never have an exact match. Because of this, scientists are continually finding more and more ways to use DNA and how this wonderful structure could be helpful in every day life.
DNA testing can be very helpful when a crime has been committed as it can point the finger at the exact person who committed the crime. By simply taking a DNA sample from the crime scene and matching it with a list of possible suspects, this eliminates any uncertainty and can prove, without a doubt, who was responsible for the crime. DNA tests, when used for these types of judicial matters, only test a very small portion of the entire DNA strand but just that tiny little piece of information is enough to convict an individual or to allow someone free who did not commit the crime but was thought of a suspect prior to the DNA tests.
DNA tests can also be extremely useful in legal paternity cases. If a woman gives birth to a child but is no longer in a relationship with the birth father, she is entitled to child support payments and if the man disputes the fact that he is actually the birth father, DNA tests can easily prove that he is the child’s father and therefore, responsible for all child support payments. These DNA tests are incredibly accurate, up to 99 or 100 percent in fact, as when a child is born their DNA is made up 50 percent from the mother’s side and 50 percent from the father’s side. The way in which the tests determine paternity or exclude it is by testing one DNA sample from the child and one from the father. If there is any similarity, the test will generally come back as “99% non-exclusion,” meaning that there is a 99% chance that the man is the father of the child. If there are no similarities between the two DNA samples, the test will come back “100% exclusion”. Even a 99% chance of non-exclusion is enough for the court to determine paternity and force the man to begin or continue making child support payments.
Individuals that are considering DNA testing should get it done as soon as they can. This can help eliminate much of the heartache and struggle that one parent is left with when another is absent, or in criminal cases where some individuals may be punished for a crime that they didn’t commit.
