Welcome to Molecular Basis of Inheritance – Part 7 (Deep Dive Series).
In this 30-minute lecture, we break down Transcription in Prokaryotes, RNA processing, and the types of RNA Polymerases exactly as per NCERT, with complete conceptual clarity.

This topic is heavily tested in NEET — especially mechanism steps, enzymes, and RNA polymerase functions.

🧬 What’s Covered in This Lecture:
🔹 Transcription in Prokaryotes

• Template vs Coding strand
• Promoter (–10 regions)
• Sigma factor + core enzyme
• Initiation → Elongation → Termination
• Rho-dependent & Rho-independent termination
• Direction of transcription (5' → 3')
• NCERT diagrams simplified

🔹 RNA Processing (Eukaryotic overview for NEET)

• Capping (7-methyl guanosine cap)
• Poly-A tail addition
• Splicing (introns vs exons)
• Importance of RNA editing for NEET

🔹 Types of RNA Polymerases

• RNA Polymerase I – rRNA (except 5S)
• RNA Polymerase II – mRNA
• RNA Polymerase III – tRNA + 5S rRNA
• Trick to never forget the functions
• NEET favourite MCQ traps

Perfect for NEET 2025/2026 aspirants mastering the Molecular Biology unit.
