Learn how DNA fingerprinting is used to identify individuals based on their unique DNA characteristics. Find out the principle, steps and applications of this technique in forensic science, paternity tests and personal identification. What is DNA Fingerprinting ? Satellite DNA regions are stretches of repetitive DNA which do not code for any specific protein. These non-coding sequences form a major chunk of the DNA profile of humans. They depict a high level of polymorphism and are the basis of DNA fingerprinting . These genes show a high level of polymorphism in all kind of tissues as a result of which they prove to be very useful in forensic studies. Any piece of DNA sample found at a crime scene can be analysed for the ... DNA fingerprinting , also known as DNA typing, DNA profiling, genetic fingerprinting , genotyping, or identity testing, is a technique used in genetics to isolate and identify variable elements within the base-pair sequence of DNA (deoxyribonucleic acid). Alec Jeffreys, a British geneticist, devised the technique in 1984 after observing that certain sequences of highly variable DNA (known as minisatellites) that do not contribute to the functions of genes are repeated within genes. Each ... DNA Fingerprinting is a technique used to identify individuals by analyzing their unique DNA patterns. Studying the DNA Fingerprinting steps and process helps in understanding genetic relationships, solving crimes, and identifying individuals based on their unique DNA profiles. In this article, we will cover DNA fingerprinting applications, uses, and steps. You can also find DNA fingerprinting notes here.
