Question

Which of the following sequence is a correct one foar meiotic cell cycle?

• A. ${{G}_{1}}\to S\to {{G}_{2}}\to M\to {{G}_{1}}$
• B. ${{G}_{1}}\to {{G}_{2}}\to M\to {{G}_{2}}$
• C. ${{G}_{2}}\to {{G}_{1}}\to S\to M\to {{G}_{2}}$
• D. $~S\to {{G}_{1}}\to {{G}_{2}}\to M\to S$

Answer 1

Answer: (A)

${{G}_{1}}\to S\to {{G}_{2}}\to M\to {{G}_{1}}$

Answer 2

The basic parts of cell cycle are interphase and M-phase or dividing phase. The interphase is metabolically the most active stage and divided into ${{G}_{1}},\text{ }S$ and ${{G}_{2}}$ phases. The correct sequence of phases in cell cycle is ${{G}_{1}}\to S\to ~{{G}_{2}}\to M\to {{G}_{1}}$
