Phototropin has two LOV domains and a kinase domain, separated by an α-helical region (Jα). In the absence of light, which one of the following is correct prediction?

#Unit 6. System Physiology – Plant
  1. the N-terminal region, including the LOV domains, “cages” and represses the activity of the kinase domain
  2. the C-terminal region, including the LOV domains, “cages” and represses the activity of the kinase domain
  3. the N-terminal region, including the LOV domains, “uncages” and re-expresses the activity of the kinase domain
  4. the C-terminal region, including the LOV domains, “uncages” and re-expresses the activity of the kinase domain

During  a  field  trip,  an  instructor  touched  a  moth  resting  on  a  tree  trunk.  The  moth  raised  its  forewings  to  reveal large eyespots on its hind wings. The instructor asked why the moth lifted its wings. One student answered that sensory  receptors  had  fired  and  triggered  a  neuronal  reflex  culminating  in  the  contraction  of  certain  muscles.  A second student responded that the behaviour might frighten predators. Which statement best describes these explanations?
