उत्तर
Finger printing with DNA is a very contemporary technology. It is employed to recognize a particular DNA pattern in an individual. It is also possible to identify criminals with this technology. An unknown or deceased person can also be identified using this method. The mother, father, and child's DNA formats must be added in order for spinach to be proven (to be matched). Fingerprinting DNA is used to determine the descent of such an illusion. When chronic relics are discovered during excavation, this method is also used to study them.
