DNA Fingerprinting
DNA Fingerprinting is a method used to identify people based on their unique DNA. DNA, or deoxyribonucleic acid, is the genetic material that makes each person special. Everyone has a different DNA pattern, like a fingerprint. Scientists collect DNA from a sample, such as blood, hair, or saliva, and analyze it to create a DNA profile. This profile can be used to match a person to a crime scene, find family members, or verify identities.
DNA Fingerprinting is very important in many areas. In law enforcement, it helps solve crimes by linking suspects to evidence. It is also used in medicine to diagnose genetic diseases and in forensics to identify victims of disasters. Additionally, DNA Fingerprinting can help people find their biological parents or relatives. This technology has made it easier to accurately identify individuals and has improved the way we use genetic information in our lives.
