Which statement about reporters is false? A. Lab-worthy GFP emits a green fluorescence when it binds and cleaves its substrate when illuminated with UV light.

B. Luciferase enzymes use luciferin substrates to yield a light (photon) signal; they are often used to measure promoter activity.

C. Beta-galactosidase is an enzyme encoded by the lacZ gene and cleaves galactosides like ONPG and X-gal to yield yellow and blue colors, respectively.

D. Alkaline phosphatase is an enzyme encoded by the phoA gene that cleaves ONPP to yield a yellow color and XP to yield blue.
