Question

In a mouse, duplication of centrioles in cytoplasm is completed in (A) S-Phase (B) G2 Phase (C) G1 Phase (D) both (B) and (C)

The cell cycle is divided into two phases - Interphase and Mitosis phase or the M phase. The interphase is further divide into 3 phases - Gap 1 or G1 phase, Synthesis phase or S phase and Gap 2 or G2 phase. G1 phase is the interval between mitosis and initiation of DNA replication during which the cell is metabolically active and grows but does not replicate. The DNA replication begins in the S phase and the centrioles duplicate in the cytoplasm. In the G2 phase, proteins are synthesised in preparation for mitosis while cell growth continues.
