The DNA fingerprint, produced by digestion of both sets of DNA by restriction enzymes, is run on an electrophoresis gel, stained, and photographed. The patterns are then compared.
The DNA finger printing can be defined as the technique or a chemical test that compares the DNA of the two different person.
In order to see the similarity between these two DNA, the result is then disclosed. This technique is commonly used for the criminal identification, blood relations, et cetera.
There are some part of DNA that is common in both the parent and the child and those parts are known as the STRs. These parts are same only in the child and the child and hence it is proven that it belongs to the parent which is being tested.
