Molecular Basis of Inheritance Part-1 | DNA, RNA & Griffith's Experiment | CUET Biology 2026

Molecular Basis of Inheritance Part-1 | DNA, RNA & Griffith's Experiment | CUET Biology 2026 Welcome back to Aspiring Aces! 🧬 We are starting a new journey into the microscopic world with Chapter 5: "Molecular Basis of Inheritance" (Part-1). In this lecture, Dr. Yashodhara Bhushan Ma'am explains why DNA is the master molecule of life and how scientists proved it. This session is vital for CUET 2026 and Class 12 Boards. We cover the chemical structure of nucleotides, the "Puri Aa Gai" trick to remember nitrogenous bases, and the classic Griffith's experiment that changed our understanding of genetics. 💡 In this video, we cover: • Introduction to Genetic Material: Qualities & Functions. • DNA vs. RNA: Primitive vs. Advanced Genetic Material. • Chemical Structure: Nitrogenous Bases (Purines & Pyrimidines). • Nucleoside vs. Nucleotide (The Base-Sugar-Phosphate Bond). • Hydrogen Bonding in DNA (A=T and G≡C rules). • Griffith's Transforming Principle (1928): The Mouse & Streptococcus pneumoniae Experiment. • Avery, MacLeod, and McCarty Experiment (1944): Biochemical Characterization of the Transforming Principle. ⏳ Timestamps (Video Chapters): 0:00 - 3:02 : Introduction to Genetic Material & Replicating Molecules 3:02 - 7:36 : Qualities of Ideal Genetic Material (Stability & Inheritance) 7:36 - 15:15 : Nucleic Acids: DNA vs RNA (Chemical Differences) 15:15 - 20:42 : Chemical Structure of Nucleotides (Base, Sugar, Phosphate) 20:42 - 26:55 : Nitrogenous Bases: Purines vs Pyrimidines & "Puri Aa Gai" Trick 26:55 - 35:58 : Nucleosides vs Nucleotides & Hydrogen Bonding in DNA 35:58 - 45:00 : Search for Genetic Material: Historical Background 45:00 - 55:29 : Griffith's Transforming Principle (1928) - Mice Experiment 55:29 - 1:02:10 : Avery, MacLeod & McCarty Experiment (1944) - DNA as the Factor ✅ Don't forget to: 👍 LIKE the video if it helped clear your concepts! 🔔 SUBSCRIBE to Aspiring Aces and hit the bell icon for the full CUET 2026 Biology series. 📲 SHARE this video with your friends preparing for Medical Entrance Exams. 📌 Connect with Aspiring Aces: If you are looking for expert guidance for CUET, NEET, or JEE, visit our center today! 📍 Address: A1/1, Prashant Vihar, Sector-14, Rohini, Delhi 📞 Call: 9266625029 | 011-44761030 🌐 Website: www.aspiringaces.in 👇 Follow us on Social Media: Instagram:   / aspiringaces_official   Facebook: https://www.facebook.com/profile.php?...
