5. A new mutation that arose in one copy of gene X in a somatic cell resulted in the formation of a tumor. Which of the following pieces of evidence best describes how the new mutation directly caused the tumor? (A) Protein X normally stimulates cell division, and the mutation created an overactive version of protein X. (B) Protein X normally activates a growth hormone receptor, and the mutation decreased the stability of protein X. (C) Protein X normally prevents passage through the cell cycle, and the mutation created an overactive version of protein X. (D) Protein X normally regulates gene expression, and the mutation created an underactive version of protein X that blocked the cell cycle.
