Fundamentals of Forensic Biology and Chemistry

Forensic science sits at the intersection of justice and analytical science, turning microscopic clues into critical evidence. Understanding how biology and chemistry apply to legal investigations is essential for anyone interested in criminology, law enforcement, or laboratory science. This text-based course guides you through the foundational concepts of forensic biology and chemistry. You will explore how investigators identify biological fluids, analyze chemical substances, and decode DNA to piece together crime scenes. By reading through detailed explanations and studying real-world analytical scenarios, you will develop a strong grasp of how science supports the modern justice system. What you'll learn: 1. Understand the fundamental role of forensic science in civil and criminal investigations. 2. Identify biological evidence and learn the chemical tests used to detect bodily fluids. 3. Explore modern DNA extraction techniques and contemporary short tandem repeat (STR) profiling. 4. Analyze toxicological samples and chemical substances using standard laboratory frameworks. 5. Examine how chain of custody and quality control preserve the integrity of scientific evidence. The course begins with core definitions and historical context, establishing a solid baseline before moving into detailed written breakdowns of laboratory methods, molecular biology, and chemical analysis techniques. It is designed for absolute beginners, aspiring criminologists, and science enthusiasts with no prior experience in forensic laboratories.
