1. Introduction to Transcription

 Transcription is the process by which genetic information from DNA is copied
into RNA.
 Central to the central dogma of molecular biology: DNA → RNA → Protein.
 Key differences between prokaryotic and eukaryotic transcription.

, 2. Structural Basis of Transcription

2.1 DNA and Promoter Structure

 Double helix structure with promoter, coding, and terminator regions.




Table: Promoter Elements in Prokaryotes vs. Eukaryotes

Feature Prokaryotes Eukaryotes

Promoter -10 and -35 boxes TATA box, INR, BRE

RNA Polymerase Single type Three types (I, II, III)


2.2 RNA Structure

 Single-stranded, various types (mRNA, tRNA, rRNA, etc.)




2.3 RNA Polymerase

 Multi-subunit enzymes
 Eukaryotic types: Pol I (rRNA), Pol II (mRNA), Pol III (tRNA, 5S rRNA)
