Based on the following information, write a detailed hypothesis for the potential experiment
y. lipolytica expresses a protein, gpr1, needed for growth on certain carbon sources. when the carbon source is depleted, gpr1 is dephosphorylated. when new carbon sources are added, half the gpr1 population is phosphorylated. if acetate is the new carbon source, all gpr1 is phosphorylated. a dominant mutant version, gpr1 d , cannot survive with acetate as the carbon source.
