In a particular organism, there are two similar genes called YFG1 and YFG2. YFG1 is expressed in the liver and not in the pancreas, and YFG2 is expressed in the pancreas but not the liver. Neither YFG1 nor YFG2 is expressed in the heart. If you extract DNA from heart cells, do you expect to see the YFG2 gene? Explain why. Do you expect to see the YFG1 protein when you analyze protein extract from liver cells? And from pancreas cells? And from heart cells? Explain why. Is it possible to produce YFG1 and YFG2 proteins via alternative splicing? Explain one possible way (mechanism) to regulate the expression of YFG1 gene.
