NEET Biology Cell Cycle and Cell Division Question Bank Self Evaluation Test - Cell Cycle and Cell Division

  • question_answer
    Mature nerve cells cannot undergo cell division. These cells are probably considered in:

    A) \[{{G}_{2}}-phase\]                  

    B) S-phase

    C) Mitosis              

    D) \[{{G}_{0}}-phase\]

    Correct Answer: D

    Solution :

    [d] Some cells in the adult animals do not show division (e.g., heart cells, and many other cells divide only occasionally i.e., when there is need to replace cells that have been lost due to injury or cell death). These cells do not divide further and exit \[{{G}_{1}}-phase\] to enter an inactive stage called quiescent stage \[\left( {{G}_{0}} \right)\] of the cell cycle. Cells in this stage remains metabolically active but no longer proliferate.
