DNA is a powerful tool and the results conclude the relationship status of two people. You can check weather two persons are related to each other or not. You can use it for civil as well as criminal cases. DNA testing can also tell about the nature of the person.

The latest advancement in DNA testing is that you can tell the age and gender of the person. DNA is present in every part of your body. You can take it from anywhere weather hair, skin, anywhere. You can accurately test anything about a person. Now people prefer DNA test instead of blood test because it is more accurate.

DNA is a molecule that makes people unique in this world. DNA testing was discovered by Prof. Alec Jeffreys of Leicester University in 1984. At this time the first test was done. Like for finger print test a comparison is made between the loops and the whorls of the suspect and actual finding same is the case when conducting the DNA test as well. In DNA testing different features of DNA are compared. These DNA features are called DNA markers.

Suppose you are comparing the markers of two DNA and get to know that both the markers are similar then you can easily get an idea that both DNA are of the same person. If the DNA markers do not match at all then the result is that there is no relationship between the persons from which the DNA is taken. And if you come to know that there are some markers that are similar to each other then the result is that there is a relationship between the two persons from which DNA is taken.

Many different cases are solved with DNA testing. The most important reasons why DNA testing is done are for the identification of the relationship between two persons and the second one is to check if the suspect is a criminal or not.

First time DNA testing was done for non criminal and legal cases like immigration and child support cases. In 2004 more than 7000 DNA tests were conducted in UK itself in order establish the truth about the relationship between the couples and the child.

DNA testing is best in determining the relationship between two individuals. It is an unquestionable proof of relatedness. The first case of DNA testing was done for a landmark immigration case in 1985. It is Sarbah vs. Home Office case. It is a mother son case in which DNA testing is done to prove the reliability of the relationship between mother and son.

Many child support agencies also use DNA testing to verify the biological parents of the child. There are many different DNA codes like AATTGCCTTTTAAAAA. Codes are passed on to the child from parents. Everybody has different code.

DNA has made the working of things easy. It is a boon to medical science. Also solving different cases has become easy. It is an interesting piece in the human body.
