How has DNA fingerprinting Changed Forensics?
To begin with, DNA stands for Deoxyribonucleic acid, a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. It is the carrier of genetic information and present in nearly all living organisms as the main
constituent of chromosomes. Before DNA fingerprint was discovered, the crime department all around the world had little forensics, or scientific methods that really helped investigators solve crime scenes. Before, the person who was guilty of a crime left no evidence, making it hard for police to find that person and put him in jail. However when DNA fingering was discovered by James Watson and Francis Crick in in the 1950s, the criminology industry and forensics was changed forever. By extracting a DNA fingerprint found in a crime scene, investigator were able to find the person who committed a crime. In addition to this, if investigators found one or more suspects in a crime, they were able to find the person who was guilty of the crime by using DNA fingerprinting. With DNA fingerprinting, crime investigators could find valuable information easier and that was more resourceful. No one could prove a DNA fingerprinting not there.
