To find the gene that encodes for the blue-light receptor,researchers inserted the gene for the PHOT1 protein into insect cells growing in culture.When they exposed the transgenic cells to blue light,they found that the PHOT1 protein became phosphorylated.No other plant proteins were present in the insect cells.Which of the following is a reasonable conclusion from this result?

Question

Quizplus · Accepted Answer

The fact that the PHOT1 protein became phosphorylated when exposed to blue light suggests that it is responsive to blue light and can phosphorylate itself. It does not necessarily indicate that the protein is functional in insect cells, photosynthetic or photoreversible, so choices A, D and E can be ruled out. Choice C is contradicted by the evidence presented in the statement.
