🧬 Avery, MacLeod & McCarty Experiment | Discovery of DNA as Genetic Material | Explained in Urdu/Hindi In this video, we explain the Avery, MacLeod, and McCarty experiment (1944) – one of the most important discoveries in molecular biology! 🧪✨ Building on Griffith's transformation experiment, these scientists worked to find out what molecule carries genetic information. Is it protein? DNA? RNA? They tested different biological molecules — proteins, RNA, carbohydrates, lipids, and DNA — by destroying them one by one in bacterial extracts. The result? When DNA was destroyed, transformation stopped. When other molecules were destroyed, it continued. ✅ This proved that DNA is the transforming principle and the true genetic material – a major breakthrough in biology! 📚 --- 🔍 Topics Covered: Griffith’s experiment recap Purpose of Avery, McLeod, McCarty's experiment Step-by-step explanation Why proteins, RNA, and other molecules were tested Final conclusion: DNA is genetic material --- 📚 Great for students of: Class 10, 11, 12 Biology (FBISE, Punjab Board, CBSE, etc.) NEET, MDCAT, Entry Tests 🎓 Language: Simple Urdu/Hindi + Easy English terms --- ✅ Don’t forget to Like 👍, Share ↗️, and Subscribe 🔔 for more science videos! #DNA #Genetics #BiologyClass11 #GriffithExperiment #AveryExperiment #Transformation #UrduBiology #FBISE #BiologyShorts #ScienceExplained #genetics #biology #chromosomes #inheritance #scienceexplained #class11th #federalboard #nbf #biologylecture
