A process called the Restriction Fragment Length Polymorphism (RFLP) was originally used in DNA testing. However, the new millennium seems to symbolize the progress and that indeed is what the DNA technology is making. The new century is setting its sights on an improved method of examining DNA known as the Polymerase Chain Reaction (PCR). Polymerase Chain Reaction is a procedure used to increase the number of copies of a specific portion of DNA, in hopes of making an adequate amount available for testing. What this means is that forensic scientists will be able to work with minute amounts of DNA evidence because they can duplicate it enough times to produce an abundant supply for observations. This will greatly facilitate the identification of an individual in criminal cases perhaps even leading to an increased number of justified convictions. Hopefully, this will ensure a safer society in the future, with a lower crime rate.
