DNA Fingerprinting: A Tool in Forensic Analysis

Ayushi Arora

Abstract: DNA (Deoxyribonucleic acid) fingerprinting methods have revolutionized the field of forensic science. We can create a person's unique genetic profile by using this method to examine the DNA region. Nowadays, DNA fingerprinting is a daily test. The DNA fingerprinting method has been in use for the last 26 years. During all these years of this method numerous changes have been made. New techniques were developed during all these years, which gives more accurate results then the previous one. The steps involved to perform this method are DNA extraction, DNA quantification, amplification of up to 23 humans short Tandem repeat and then splitting them on capillary column and the last stage is interpretation of data which is followed by reporting the evidence in the court. This study looks at how different DNA fingerprinting techniques may be used to distinguish between blood samples collected from different people. To accomplish a complete approach to person identification, the study combines standard blood grouping, RBC and WBC cell count analysis, and sophisticated Short Tandem Repeat (STR) and Restriction Fragment Length Polymorphism (RFLP) approaches. The study's goal is to show how successful these strategies are in forensic to differentiate between individuals.
