Which of the phases of cell cycle is of longest duration?

Explanation

To determine which phase of the cell cycle is of the longest duration, we need to analyze the different phases involved in the cell cycle. The cell cycle consists of the following phases:

1. **G1 Phase (Gap 1)**: This is the first phase of the cell cycle where the cell grows and carries out normal functions. The duration of the G1 phase is approximately 8 to 10 hours.

2. **S Phase (Synthesis)**: During this phase, DNA replication occurs, resulting in the duplication of chromosomes. The duration of the S phase is about 6 to 8 hours.

3. **G2 Phase (Gap 2)**: This phase follows DNA synthesis and involves further growth and preparation for mitosis. The duration of the G2 phase is approximately 4 to 6 hours.
