All about DNA Tests and Applications.

DNA testing has become very common today despite being discovered not long ago, its use in the criminal justice system and other fields has made identification of persons very easy.

In the next couple of years a strand of hair will not only tell the identity of the person but it will also narrow down to the age of the person as well. Before there was DNA testing human identity was through blood typing. DNA testing tends to be more accurate than blood typing and that makes it more preferable. DNA testing is based on a comparison of DNA features that will never be similar to another set between two people not even identical twins.

Even when using DNA fingerprinting the loops and whorls are like a personal signature that only belongs to one person. In DNA testing if the samples’ patterns are identical then they are likely to be from the same person.
