Question 4

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?

Accepted Answer

A)  The PHOT1 protein is photoreversible. 
B)  The PHOT1 protein phosphorylated itself in the presence of blue light. 
C)  The PHOT1 protein is not responsive to blue light. 
D)  The PHOT1 protein is not functional in insect cells. 
E)  The PHOT1 protein enabled the insect cells to photosynthesize. 
A)  The PHOT1 protein is photoreversible. 
B)  The PHOT1 protein phosphorylated itself in the presence of blue light. 
C)  The PHOT1 protein is not responsive to blue light. 
D)  The PHOT1 protein is not functional in insect cells. 
E)  The PHOT1 protein enabled the insect cells to photosynthesize.
