NEET Botany Question (2026) — Solution

Question

The correct sequence of adult cell cycle phases is __________.

Options

  1. A. S-M-G2-G1
  2. B. G1-G2-S-M
  3. C. G1-M-G2-S
  4. D. G1-S-G2-M

Answer

D. G1-S-G2-M

Step-by-step solution

The cell cycle is divided into two basic phases: Interphase and M Phase (Mitosis phase). Interphase is further divided into three phases: G1 phase (Gap 1): The cell is metabolically active and continuously grows but does not replicate its DNA. S phase (Synthesis): DNA replication takes place. G2 phase (Gap 2): Proteins are synthesised in preparation for mitosis while cell growth continues. Following interphase, the cell enters the M phase where actual cell division occurs. Therefore, the correct sequence of the cell cycle phases is G1-S-G2-M.
