Number of centrioles after completion of the G2 phase and during the metaphase of mitosis is _ and _ respectively.
Correct answer: C. 4,4
- A. 2,2
- B. 2,4
- C. 4,4
- D. 4,2
Explanation
Number of centrioles after completion of the G2 phase and during the metaphase of mitosis is 4 and 4 respectively. During S phase of the cell cycle, the centrosomes replicate. Each centrosome contains 2 centrioles. Since now there are 2 centrosomes, the total number of centrioles will be 4. G2 phase comes right after the S phase and during metaphase cytokinesis has not occured as a result, the cell contains 4 centrioles in both of these stages.
