It is the most recent technique that is done to compare the DNA of individuals. In this technique, the nuclear DNA is taken from the sample of blood and then selected regions of the DNA are amplified using the polymerase chain reaction. After that the STR sites are identified then it is compared to find that the two samples belong to the same person or not.
