Homework Answers
The correct answer is option A. The function of Rb (retinoblastoma) is to prevent excessive cell growth by inhibiting cell cycle progression until a cell is ready to divide. When the cell is ready to divide, Rb is phosphorylated to pRb, leading to the inactivation of the activity of Rb. This process allows cells to enter into the cell cycle state. Therefore, the cell cycle will start and a high amount of cell division wil occur.
