Given some observation of the auxin signalling pathway, which one of the following are the incorrect prediction about signalling?

#Unit 6. System Physiology – Plant
  1. auxin receptor gene family, TIR1/AFB1-5, encode F-box components of the SCF complex that functions in the degradation of AUXIN/INDOLE-3-ACETIC ACID (AUX/IAA) 
  2. Auxin-responsive genes typically have auxin response element (AuxRE) binding sites located in their promoter regions
  3. Auxin response factors (ARFs) are transcription factors that bind to these AuxRE motifs only stimulate transcription
  4. Auxin response factors (ARFs) are transcription factors that bind to these AuxRE motifs to stimulate or repress transcription

Fred and Joe, two unrelated, mature male gorillas, encounter one another. Fred is courting a female. Fred grunts as Joe comes near. As Joe continues to advance, Fred begins drumming (pounding his chest) and bares his teeth. Joe then rolls on the ground on his back, gets up, and quickly leaves. This behavioural pattern is repeated several times during the mating season. Choose the most specific behavior described by this example
