In your molecular biology class, you make two different cDNAs. The first cDNA expresses a green fluorescence protein (GFP) fused to the retinoid hormone receptor. The second cDNA expresses a red fluorescent protein (RFP) fused to the glucocorticoid receptor. You express both cDNAs in the same mammalian cell in a dish and examine their appearance using a microscope equipped with fluorescence optics. Then, you add retinoid and glucocorticoid ligands to the dish and wait for 30 minutes before re-examining the cells. Which colors would be seen in the nucleus and the cytosol before and after the addition of the ligands?
