Question
UVR8 lacks which component?
Explanation
That points to B: Chromophore. Compared with the other options, Chromophore is the one that correctly describes the PSS-Sec-E-Sensory biology concept. The wrong ones are A) Dimer structure; C) Tryptophan residues; D) β-propeller fold. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.
