When Ras is activated, cells will divide. A dominant-negative form of Ras clings too tightly to GDP. You introduce a dominant-negative form of Ras into cells that also have a normal version of Ras. Which of the following statements is TRUE? O a. The normal Ras in the cells you create will not be able to bind GDP because the ion dominant-negative Ras binds to GDP too tightly. O b. The cells you create will divide more frequently compared to normal cells in response to the extracellular signals that typically activate Ras. C. The cells you create will divide less frequently than normal cells in response to the extracellular signals that typically activate Ras. O d. The cells you create will run out of the GTP necessary to activate Ras. Clear my choice

When Ras is activated, cells will divide. A dominant-negative form of Ras clings too tightly
to GDP. You introduce a dominant-negative form of Ras into cells that also have a normal
version of Ras. Which of the following statements is TRUE?
O a. The normal Ras in the cells you create will not be able to bind GDP because the
ion
dominant-negative Ras binds to GDP too tightly.
O b. The cells you create will divide more frequently compared to normal cells in
response to the extracellular signals that typically activate Ras.
c. The cells you create will divide less frequently than normal cells in response to the
extracellular signals that typically activate Ras.
O d. The cells you create will run out of the GTP necessary to activate Ras.
