Researchers wanted to study if 2 proteins Q and R come close enough to interact with each other in the presence of high levels of cAMP. In a FRET experiment, protein Q was fused to CF and protein R was fused to YFP. Both these gene fusions were transfected into COS cells. So, when cAMP levels rise and the cells were illuminated using 440 m light, the predominant emission was at 490m. How would you interpret this result? .
