Given below are two statements: Statement I: During G 0 phase of cell cycle, the cell is metabolically inactive. Statement II: The centrosome undergoes duplication during S phase of the interphase. In the light of the above statements, choose the most appropriate answer from the options given below:

Step-by-step solution

Some cells, after the mitotic phase exit from the G1 phase and enter the inactive stage called quiescent stage (G 0 ) of the cell cycle. Cells in this stage remain metabolically active but no longer proliferate unless called on to do so depending on the requirement of the organism. In the S phase of interphase, the cells duplicate their DNA. In animal cells, during the S phase, DNA replication begins in the nucleus, and the centriole duplicates in the cytoplasm.
