Question

How can DNA finger printing be applied to solve a murder mystery

Answer 1

A sample of biological material can be collected from the crime scene. It will probably contain the material from the victim and crime. Knowing the DNA fingerprint of the victim, it is possible to identify the fingerprint of the murderer. If there are several suspected persons, DNA fingerprint identified from the murderer can be compared to DNA fingerprints of the suspected persons. Moreover, if there is a database of DNA fingerprints, the murderer can be identified immediately by comparing the obtained fingerprint with all the ones present in database.
