Biotechnology in Forensic Science: How DNA Helps Solve Criminal Cases A single hair or drop of blood can now solve a crime that once seemed impossible to crack. Investigators used to rely on eyewitnesses and fingerprints alone. Those tools often left cases unsolved for years. Today, biotechnology gives forensic scientists a far more precise way to identify suspects and clear the innocent. This shift didn't happen overnight. Decades of research in molecular biology built the tools crime labs use now. Scientists learned how to copy, read, and compare tiny DNA fragments with incredible accuracy. That expertise now powers everything from cold-case breakthroughs to courtroom testimony. In this article, you'll learn how DNA evidence moves from a crime scene to a courtroom. We'll walk through collection, lab analysis, and legal use. You'll also see the history, limits, and ethics behind forensic DNA testing. Quick Answer Biotechnology helps solve crimes by tur...
