Question

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

• A. G₂ → G₁→ S →M →G₂
• B. G₁→ G₂→ S →M →G₂
• C. G₁→ S →G₂→ M →G₁
• D. S→ G₁→ G₂→ M →S

Answer 1

The correct option is C

G₁→ S →G₂→ M →G₁

The regular sequence of G₁, S, G₂ (interphase) and M (mitotic) phase is called the cell cycle. A cell undergoing meiosis will first enter the G₁ phase, followed by the S phase, then G₂ phase and finally undergo meiosis. The cells which divide further re-enter the G₁ phase and the cycle continues. The cells which do not divide do not proceed beyond the G₁ phase but start differentiating by entering the G₀ phase.
