DNA Profiling Explained | HSC Biology Made Simple

🧬 DNA Profiling | HSC Biology Case Study A woman is found dead. Blood on the floor. Two suspects—one says he was never there. But DNA doesn’t lie. In this video, we break down how DNA profiling can turn suspicion into certainty using Short Tandem Repeats (STRs). You’ll learn how forensic scientists: ✅ Use PCR to amplify STR regions ✅ Run gel electrophoresis to compare genetic fingerprints ✅ Match suspects to crime scenes based on unique DNA banding patterns We’ll also explore a real-life case where DNA profiling led to a wrongful conviction—and what that means for how we use this powerful tool in science and justice. Plus: ✔️ Paternity & maternity testing ✔️ Identifying disaster victims ✔️ Monitoring endangered species This is everything you need to know about DNA profiling for HSC Biology—delivered through story, science, and suspense. 🎓 Perfect for HSC Module 6: Genetic Change 📚 Great for students aiming for a Band 6 🔍 Learn how to answer DNA profiling questions with real examples 📌 Don’t forget to like, comment your questions, and subscribe for more HSC Biology breakdowns! #HSCBiology #DNAProfiling #Forensics #GeneticChange #STRs #PCR #GelElectrophoresis #ScienceYouCanUse #Band6Biology
