Practice question
Question
Auxin signaling involves degradation of which protein?
Explanation
Go with C — AUX/IAA. Under Auxin Phytohormone, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) ARF; B) PIN; D) YUCCA. When two options sound similar, choose the one that matches the textbook definition most tightly.
