Biology · CELL CYCLE AND CELL DIVISION

हिन्दी

Which of the following physiological states accurately describes cells entering the quiescent stage (G0) of the cell cycle?

  1. They permanently lose their metabolic activity and enter apoptosis
  2. They duplicate their centrosome and arrest permanently at G2 phase
  3. They replicate DNA continuously without undergoing cell division
  4. They exit G1 phase, remain metabolically active, but cease proliferation unless stimulated

Correct answer · Option 4

They exit G1 phase, remain metabolically active, but cease proliferation unless stimulated

Explanation

Cells that do not divide further exit G1 phase to enter the inactive quiescent stage (G0); they remain metabolically active but no longer proliferate unless called on depending on the requirement of the organism.
