### Video Description

**Master Transcription & the Central Dogma of Biology\!** 🧬📖

In this detailed lecture for Class 12 Biology (Chapter 4), we dive deep into the **Molecular Basis of Inheritance**. Learn exactly how genetic information flows from DNA to Protein and master the complex process of **Transcription**—a must-know topic for your Board Exams\!

**In this video, we cover:**
✅ **The Central Dogma:** Understanding the flow of life (DNA ➡️ RNA ➡️ Protein) as proposed by Francis Crick.
✅ **Transcription Basics:** What it is, where it happens (Nucleus), and the role of RNA Polymerase.
✅ **Transcription Unit:** Detailed breakdown of the Promoter, Structural Gene, and Terminator.
✅ **Process of Transcription:** Step-by-step explanation of Initiation (Sigma factor), Elongation, and Termination.
✅ **Post-Transcriptional Modifications:** Understanding HnRNA, Splicing (Exons vs. Introns), Capping, and Tailing.
✅ **Retro-viruses:** How Reverse Transcription works in viruses like HIV.

Whether you are preparing for your **12th Board Exams (HSC/CBSE)** or competitive exams like **NEET**, this lecture simplifies complex biological concepts with easy-to-understand diagrams and Hindi-English explanations.
