If you place a kidney specific enhancer element in front of a lac z reporter gene in insert into a mouse chromosome. what would you expect to see in the adult mouse if you fed it a diet that contained xgal?

The expression of kidney specific enhancer element will help in the growth of kidney cells in mouse.

Explanation:

Reporter gene is a specific type of gene that reports the success of cloning.According to the given question,if the kidney specific enhancer element is expressed inside the mouse then it will help in the stimulation of cell growth of mouse"s kidney.

   On the other hand if the reporter gene lacZ  is expressed then it will encode β D  galactosidase which will act on the given substrate Xgal.This reaction will ultimately result in the blue coloration due to the breakdown of X gal.
