What Is DNA Fingerprinting In Crime Scene Investigation? Have you ever wondered how investigators identify individuals involved in a crime using biological evidence? In this informative video, we'll explain the process of DNA fingerprinting and its vital role in crime scene investigations. We'll start by describing how biological samples like blood, hair, saliva, or skin cells are collected from crime scenes and prepared for analysis. You'll learn about the laboratory techniques used to amplify tiny amounts of DNA, making it possible to analyze even the smallest samples. We will also discuss how scientists examine specific regions of DNA called short tandem repeats (STRs), which vary from person to person, to create a unique DNA profile. Additionally, we’ll cover how DNA profiles are compared with those from suspects or stored in databases to identify or exclude individuals. We’ll explain why this method is considered highly reliable and how it has revolutionized forensic science by providing accurate, fast, and minimally invasive identification. Whether it’s solving crimes, identifying victims, or linking multiple cases, DNA fingerprinting has become an essential tool for justice. Join us for this detailed overview, and subscribe to our channel for more insights into the fascinating world of biology and forensic science.
