Genetic Fingerprinting – How DNA Helps Solve Crimes

28.02.2025

Every person has a unique DNA, except for identical twins. Scientists can analyze specific parts of DNA to create a genetic fingerprint, which is like a code that makes each person different. This technique is used in forensic science to help solve crimes. If a criminal leaves behind DNA at a crime scene—like a hair, skin cell, or drop of blood—experts can compare it to suspects and find a match.

But forensic DNA testing is not just for crime-solving. It is also used to identify missing persons, prove family relationships, and even help innocent people who were wrongly convicted. Since DNA remains the same throughout life, genetic fingerprints can solve even decades-old cases. Thanks to this powerful tool, forensic scientists and police can use biology to uncover the truth and bring justice!
