General Awareness PYQs

The correct answer is It is a temporary quiescent stage where cells exit the cell cycle..

Key Points

• The GO phase (G zero phase) represents a state of cell cycle arrest, where cells exit the active cycle and stop dividing.
• Cells in the GO phase are in a non-proliferative or quiescent state, often performing specialized functions depending on the cell type.
• This phase is temporary or permanent, depending on the cell type and environmental conditions.
• Examples of cells in permanent GO phase include neurons and skeletal muscle cells, which do not divide after differentiation.

• GO phase is not part of the active cycle and is considered a resting state.
• Quiescence vs Senescence:
• Quiescence refers to reversible cell cycle arrest (GO phase).
• Senescence is an irreversible state of cell cycle arrest caused by damage or aging.
• Role in Cancer:
• Cancerous cells often evade GO phase, leading to uncontrolled division and tumor formation.
• Targeting the mechanisms regulating GO phase is a focus in cancer therapy research.
• Cell Types:
• Stem cells can exit GO phase to re-enter the cycle and divide.
• Terminally differentiated cells like neurons remain in GO phase permanently.
