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

 Following figure are shown figure of predator prey model 


Following some observation are given

A) The number of prey, N, increase at low predator densities, P, and decrease at high predator densities

B) Prey zero isoclines is depends on the ratio of the growth rate of prey to the capture efficiency of the predators

C) Number of predator needed for prey isoclines is depends on the ratio of the death rate of predators to the conversion efficiency of predators

D) Number of predator for prey isoclines depends on the ratio of the death rate of prey to the conversion efficiency of predators
