The correct sequence of adult cell cycle phases is __________.
- AS-M-G2-G1
- BG1-G2-S-M
- CG1-M-G2-S
- Correct answerDG1-S-G2-M
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.
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.
Hence, the correct answer is option: 'D'.
