Detailed explanation-1: -This is because once they reach maturity, nerve and heart cells do not divide again, so they stay in the G0 phase.
Detailed explanation-2: -Cells in the G0 phase are not actively preparing to divide. The cell is in a quiescent (inactive) stage that occurs when cells exit the cell cycle. Some cells enter G0 temporarily until an external signal triggers the onset of G1. No more DNA replication or cell division happens at this phase.
Detailed explanation-3: -So the correct answer is ‘G0 phase’.
Detailed explanation-4: -The correct answer is A) G0 phase of the cell cycle. G0 is a quiescent phase of the cell cycle in which cells are no longer dividing. In G0, cells can focus all their energy on metabolism and performing highly specialized functions.
