DNA PROFILING Meaning and
Definition
-
DNA profiling, also known as genetic fingerprinting or DNA testing, is a scientific technique used to analyze and compare the genetic material found within an individual's cells. It involves examining specific regions of a person's DNA sequence, which contain unique patterns of genetic markers known as short tandem repeats (STRs). These STRs are highly individualized, making them a powerful tool for identifying and distinguishing individuals from one another.
The process of DNA profiling begins by extracting DNA from a sample, such as blood, saliva, or hair, and isolating the specific regions of interest. The isolated DNA is then amplified using a polymerase chain reaction (PCR) to produce numerous copies. The amplified DNA is subjected to a process called gel electrophoresis, where it is separated based on size and charge. The resulting DNA fragments are visualized as distinct bands on a gel, creating a unique pattern or genetic profile for each individual.
DNA profiling has a wide range of applications, most notably in forensic science. It is commonly used in criminal investigations to match DNA evidence collected from crime scenes to potential suspects. It can also be utilized in paternity testing, immigration cases, and disaster victim identification. Since DNA is inherited, profiling can establish biological relationships and assist in determining familial connections.
Overall, DNA profiling is a valuable tool for the identification and differentiation of individuals based on their unique genetic makeup. It has revolutionized the field of forensic science and continues to be a crucial technique in various fields of research and identification.

Etymology of DNA PROFILING
The term "DNA profiling" is derived from various sources.
1. DNA: DNA stands for deoxyribonucleic acid, which is a complex molecule found in the cells of all living organisms. It carries the genetic information that determines the physical traits, characteristics, and functioning of an organism.
2. Profiling: The term "profiling" is derived from the verb "to profile", which means to create a profile or a detailed summary or description of a person, object, or process. In the context of DNA profiling, it refers to the process of creating a unique genetic profile or fingerprint of an individual based on their specific DNA sequence.
The term "DNA profiling" was coined and popularized in the 1980s when geneticists and forensic scientists began using DNA analysis techniques for identifying individuals and solving criminal cases.
