Forensic DNA testing can be effectively used for determining the identity of individuals with the help of DNA sequences. Samples can be collected from crime scenes or disaster spots to determine the identities of the people involved. Broadly, forensic DNA testing procedure could be of two types, RFLP based testing and the PCR based technique. The latter most often requires less amount of DNA to produce accurate results and can even provide results if the DNA has partially degraded, which is most often the case, especially during natural disasters. Types of Forensic DNA Testing RFLP based processes: This type of test requires more DNA and cannot accommodate significant degradation. It is also considered to produce more accurate results than the PCR procedure. This test looks for base pair sequences within a section of a DNA strand. Once a match is found between the base pair tested and the base pair found in an individual, there can be no doubt about the identity of the donor of the sample. PCR based tests: Although not as accurate, this procedure requires lesser DNA than RFLP. The reality is that DNA does get contaminated, both at a crime scene and even in the controlled environment of a laboratory. Given this fact, as well as the more rapid results obtained through this procedure, PCR is steadily replacing RFLP as the preferred test. Objectives of Forensic DNA Testing These test results have often proved to be successful in providing numerous breakthroughs with respect to individual identification. 1. These processes have been effectively used for identifying potential suspects from the scene of a crime, which has proved to be effective clues for zeroing in on the right suspects. They can also be used for exonerating suspects who have been falsely implicated in crimes. 2. Forensic DNA testing results are crucial for cases of organ transplants, where the donor and the recipient’s DNA need to match for a successful operation. 3. This test is also used to detect bacteria or micro organisms that are responsible for contaminating air, water, food substances and soil. 4. Forensic DNA tests also have a crucial role to play for determining the identity of victims of disasters and crimes. They can prove especially helpful if a large number of people happen to be affected. 5. DNA evaluation is also used for determining the pedigree of livestock breeds and for identifying wildlife species. It also helps in distinguishing the endangered species from the protected ones, thus providing useful inputs for wildlife enthusiasts.
