Practice question
Question
Which LOV domain is crucial for kinase activation?
Explanation
Go with B — LOV2. Under Phototropin+All, 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) LOV1; C) Both equally; D) Neither. When two options sound similar, choose the one that matches the textbook definition most tightly.
