Question

some dividing cells exist the cell cycle and ​

Answer 1

Some dividing cells exit the cell cycle and enter vegetative inactive stage. This is called quiescent stage G_(o). This process occurs at the end of G_(1) phase.

Detailed explaination:

Some cells do not need continuous proliferation via cell division.

In that case some cells exit from the cell cycle at the end of the Gap_(1) and become dormant by entering the G_(0) phase.

These cells again enter the cell cycle only when the proliferation of the cells are required during extensive damage to the other cells.

This phase is also called the resting phase, where the cells stay outside the replicative cycle.
