You have a cell line that expresses both the GPCR-X, GPCR-Y, the corresponding G-proteins, and adenylate cyclase. There is a basal level of adenylate cyclase activity that produces a baseline cAMP concentration. Your project is to characterize a series of mutations in these components. Requried:
Will each mutation increase or decrease the intracellular levels of cAMP upon ligand addition (remember, both GPCR-X and GPCR-Y bind to the same ligand)

There are few cells in the body that do not undergo mitosis: most somatic cells divide regularly, some more than others. take for example the cells that line the digestive tract. these cells must be frequently replaced because they are constantly eroded by the movement of food through the tract. what mechanism(s) is/are in place to ensure that these cells are exact copies of the mother cell
