Show Hint
Mnemonic: âDog (D) Barks (B) For (F) Every (E) Human (H)â to remember the binding order.
Updated On: May 28, 2026
- A, B, C, D and E
- A, C, B, D and E
- B, A, D, C and E
- B, C, D, E and A
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Initiation of eukaryotic transcription requires assembly of a Pre-Initiation Complex (PIC). Step 2--3: Analysis
TFIID (B) binds the TATA box first, followed by TFIIB (A). TFIIF (D) brings RNA Pol II. Finally TFIIE (C) and TFIIH (E) join to complete the complex.
Step 4: Conclusion
The assembly order is TFIID $\to$ TFIIB $\to$ TFIIF $\to$ TFIIE $\to$ TFIIH.
Final Answer: (C)
