Question

Match the specific cell cycle phases in Column-I with their corresponding events or characteristics in Column-II.

Column-I (Phase)	Column-II (Event/Characteristic)
A. G1 Phase	1. DNA replication occurs and centriole duplicates in the cytoplasm.
B. S Phase	2. Proteins are synthesized in preparation for mitosis while cell growth continues.
C. G2 Phase	3. Cells remain metabolically active but do not proliferate (Quiescent Stage).
D. G0 Phase	4. Cell is metabolically active and grows continuously but does not replicate DNA.

Accepted Answer

Correct Option: A) A-4, B-1, C-2, D-3

A-4 (G1 Phase): This is the interval between mitosis and the initiation of DNA replication. The cell is metabolically active and grows but does not replicate its DNA.
B-1 (S Phase): This is the Synthesis phase where DNA replication takes place. The amount of DNA doubles, and in animal cells, the centriole duplicates.
C-2 (G2 Phase): During this gap phase, specific proteins are synthesized in preparation for mitosis while cell growth continues.
D-3 (G0 Phase): Also known as the Quiescent Stage. Cells that exit the G1 phase enter this inactive stage where they remain metabolically active but do not divide
