Question

Once nerve cells become mature, they do not typically undergo cell division. Based on your knowledge of the cell cycle, you might predict that mature cells become arrested in the _______ of the cell cycle.

Answer 1

Mature nerve cells, as well as other cells that never or rarely divide, remain arrested in the Go phase of the cell cycle.

Step-by-step explanation:

Mature nerve cells, as well as other cells that never or rarely divide, remain arrested in the Go phase of the cell cycle.

The Go phase is a quiescent (inactive) stage that occurs when cells exit the cell cycle and are not actively preparing to divide. Some cells enter Go temporarily until an external signal triggers the onset of G₁, while others, like mature nerve cells, remain in Go permanently.

This arrest in the Go phase allows mature cells to continue functioning and performing their specialized roles without dividing.
