A Putative Regulatory Sequence Is Fused to an Enhancerless GFP

A putative regulatory sequence is fused to an enhancerless GFP gene in a reporter construct and that construct is then used to generate a transgenic organism.If the putative regulatory sequence contains an enhancer that binds with an eye-specific combination of activators, how will the transgenic organism look?

A) The entire body will glow green at all times.
B) Only the eyes will glow green at all times.
C) Only the eyes will glow green when exposed to a particular wavelength of light.
D) No parts of the transgenic organism will glow green.
