DNA Profiling Test – Understanding Its Role, Process, and Applications
In today’s world, science has opened doors to discoveries that were once unimaginable. One of the most revolutionary breakthroughs in biology and forensic science is DNA profiling or genetic fingerprinting. It has changed the way we understand human identity, heredity, and relationships. From solving criminal cases to establishing family ties, genetic fingerprinting has become an essential tool across multiple fields. What is DNA? DNA stands for Deoxyribonucleic Acid, the molecule that carries the genetic instructions necessary for growth, functioning, and reproduction of all living organisms. Each person has a unique DNA structure, except for identical twins. This uniqueness makes DNA the best biological marker to confirm identity, biological relationships, or even detect health risks. How is This Test Conducted? The process of DNA fingerprinting involves multiple steps, each carried out with great precision: Sample Collection A small sample of biological material is collected, such ...
