What Role Does DNA Play In Forensic Cold Cases? - Biology For Everyone

What Role Does DNA Play In Forensic Cold Cases? Have you ever wondered how scientists solve cold cases that have remained unsolved for years? In this informative video, we'll explain the vital role that DNA plays in forensic investigations. We'll start by discussing what DNA is and why it is unique to each individual. You'll learn how biological evidence such as blood, saliva, hair, and skin can be preserved for decades, allowing investigators to analyze even the tiniest or most degraded samples.

We'll explore how advancements in DNA technology enable the extraction of usable genetic material from old evidence, providing new opportunities to solve long-standing cases. You’ll discover how DNA profiles are compared to extensive forensic databases to identify suspects or link different crimes. Additionally, we’ll explain how DNA evidence can exonerate innocent individuals and help bring justice to victims.

Moreover, we’ll introduce familial DNA searching and genetic genealogy, innovative techniques that expand the possibilities of solving cases involving unidentified remains or unknown perpetrators. Whether you're interested in forensic science, criminal justice, or just curious about how technology is changing investigations, this video will provide you with a clear understanding of DNA’s powerful role in solving cold cases.
