DNA fingerprinting is used in the legal world to determine parentage, genealogy, or other genetic relationships, or to implicate suspects in law enforcement investigations involving violent crimes. Fragments produced by various restriction enzymes from a number of different loci can be used to identify individuals with the accuracy of a finger print. Therefore, this technique is called “Fingerprinting”.

A. They are site specific endonucleases

B. The restriction sites are palindrome in nature

C. All restriction enzymes are of bacterial origin

D. They always produce complementary single stranded overhangs

E. They are also called “molecular scissors”.
