L20: How Scientists Cracked the Genetic Code! 🧬 Molecular Biology | CSIR NET June 2026 | IFAS
🧬 How did we learn the language of life? 🧬 In Lecture 20 of our Molecular Biology series, we explore the historic experiments that allowed scientists to "crack" the Genetic Code. Before modern DNA sequencing existed, pioneers like Marshall Nirenberg, Heinrich Matthaei, and Har Gobind Khorana used ingenious biochemical methods to discover which codons encode which amino acids. This session is vital for anyone preparing for CSIR NET June 2026, GATE, DBT, and SET Life Sciences. We break down the classic experiments so you can master the logic behind the codon table! 📌 Key Topics Covered Today: ✅ Historic Context: Molecular Biology in the 1960s (Pre-DNA Sequencing era). ✅ Marshall Nirenberg & Heinrich Matthaei’s Cell-Free Translation System. ✅ The use of Artificial mRNA (Poly-U, Poly-A, Poly-C) to identify amino acids. ✅ How the Genetic Code was systematically mapped. ✅ Insight into the discovery of PCR by Kary Mullis. ✅ Strategy for mastering Unit 3: Fundamental Processes. 🔥 Join India's Best Life Science Coaching - IFAS Online! 🔥 Super Emotion Batch 7.0 Live Online Batch: Starts on 2nd Feb 2026 🔥 Offline Batches at Jodhpur/Pune: Starts on 11th Jan 2026 Proposed_Revised_Syllabus_Life_Sciences_and_Biotechnology_LS_BT:-https://drive.google.com/file/d/11EQO... 🎯 Why IFAS is India's No. 1 Choice?
