#Question id: 26534

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

#Unit 6. System Physiology – Plant

During Brassinosteroid (BR) signal transduction pathway two forms exist,
1) In absence of Brassinolide
2) In presence of Brassinolide
a) BKI1 is phosphorylated and dissociates from the plasma membrane
b) BRI1 phosphorylation, and promotes BRI1–BAK1 heterodimerization, bringing their cytoplasmic domains together for interaction, transphosphorylation
c) BRI1 and BAK1 can form homodimers and both undergoes endocytosis and recycling
d) BIN2 kinases Phosphorylate transcriptional factor BES1 and BZR1 and these Phosphorylated proteins are shortlived and are degraded in the proteasome
e) BSK proteins activate BSU1 phosphatase which dephosphorylated BIN2 is degraded by the proteasome system
f) In absence of BIN2, dephosphorylated  transcriptional factor BES1 and BZR1 form heterodimers with different transcription factors and bind E-box sequences to activate genes.
