The sequence of the cell cycle is

Options

A. `M,G_1,G_2 and S`
B. `G_1,G_2,S and M`
C. `S,M,G_1 and G_2`
D. `G_1,S,G_2 and M`

Explanation

### Step-by-Step Solution:

1. **Understanding the Cell Cycle**: The cell cycle is a series of events that a cell goes through as it grows and divides. It consists of various phases that prepare the cell for division.

2. **Phases of the Cell Cycle**: The cell cycle is divided into two main parts:
- **Interphase**: This is the phase where the cell spends most of its time (about 95%). It consists of three sub-phases:
- **G1 Phase (Gap 1)**: The cell grows and synthesizes proteins and organelles necessary for DNA replication.
- **S Phase (Synthesis)**: The cell replicates its DNA, so that each daughter cell will have a complete set of chromosomes.
- **G2 Phase (Gap 2)**: The cell continues to grow and prepares for mitosis. It checks for any errors in DNA replication and ensures all necessary components are ready for division.

3. **M Phase (Mitotic Phase)**: This is the phase where actual cell division occurs. It can be further divided into:
- **Mitosis**: The process where one cell divides to form two identical daughter cells.
- **Cytokinesis**: The final step where the cytoplasm divides, resulting in two separate cells.

4. **Correct Sequence of the Cell Cycle**: The correct order of the phases in the cell cycle is:
- G1 Phase → S Phase → G2 Phase → M Phase.

5. **Conclusion**: Therefore, the correct sequence of the cell cycle is G1, S, G2, and M.
