#Question id: 12199


Some given statements about Auxin signalling pathways are listed;
a) The auxin receptor is composed of two proteins: the SCF complex component TIR1 and the repressor protein AUX/IAA
b) The binding of auxin to its receptor complex initiates ubiquitin-dependent degradation of the AUX/ IAA repressor protein by the 26S proteasome 
c) TIR1 recruits AUX/ IAA proteins to the SCFTIR1  complex in an auxin-independent manner
d) AUX/IAA proteins are ubiquitinated by the E3 ligase activity of the SCFTIR1 complex, which marks the protein for destruction by the 26S proteasome
Which of the following is correct explanation of Auxin signalling pathways?
