Feedback regulation represents another key mechanism employed to attenuate a response such as

a) AUX/IAA proteins can bind to the promoters of their own genes and repress their own expression

b) auxin signaling triggers the degradation of AUX/IAA repressors, the ensuing transcription of auxin response genes leads to the replacement of AUX/IAA proteins and thus to response attenuation or termination

c) AUX/IAA genes, which encode the AUX/IAA auxin repressor proteins, have auxin response element binding sites located in their promoter regions

During the feedback regulation mechanism of auxin several responses are trigger, find out the correct sequences of these responses.
