Q.
Spinal cord injuries are difficult to treat because damaged nerce cells do not regenerate. Which of the following most accurately explains why damaged nerve cells no longer regenerate?
answer choices
Mature nerve cells are in a resting state; the no longer divide during mitosis
Nerve damage disrupts the cell cycle at the G1 phase
