What is the longest part of the cell cycle?

• A. Mitotic phase
• B. Interphase
• C. G1 phase
• D. Go phase

Answer: (B)

Interphase is indeed the longest part of the cell cycle, comprising the phases that a cell undergoes before it divides. This phase is crucial for cell growth, DNA replication, and preparation for mitosis. Interphase is typically broken down into three sub-phases: G1 (gap 1), S (synthesis), and G2 (gap 2), each fulfilling specific roles in the preparation for cell division. During the G1 phase, the cell grows and synthesizes proteins necessary for DNA replication. In the S phase, the cell duplicates its DNA, ensuring that each daughter cell will have a complete set of chromosomes. Finally, in the G2 phase, the cell continues to grow and produces proteins needed for mitosis, while also ensuring that all DNA is intact and can be properly divided. In contrast, the mitotic phase, which includes the processes of prophase, metaphase, anaphase, and telophase, is relatively short as it involves the actual division of the cell. The G1 phase, while it can be long, is only one component of interphase. The Go phase is a specialized state where cells exit the active cycle and enter a quiescent state, but this does not typically represent a phase
