Which of the following is incorrect order of binding of TBP

#Unit 3. Fundamental Processes
  1. In TATA – containing promoter first TBP bind and then binding of TAFs takes place
  2. In TATA less promoter with Inr and DPE  –  first TAFs binding takes place and then TBP bind
  3. In TATA less promoter with GC boxes – GC box recognizes Sp1 and Sp1 bind with TAFs and then bind of TBP takes place 
  4. In TATA less promoter with GC boxes – GC box recognizes  TAFs and TAFs bind with Sp1 and then bind of TBP takes place
