Understand that the cell cycle is divided into two main parts: interphase and the mitotic (M) phase. Interphase is the phase where the cell prepares for division, while the M phase is where the cell actually divides.
Recall that interphase is further divided into three distinct phases: G1 phase (Gap 1), S phase (Synthesis), and G2 phase (Gap 2). These phases are collectively known as interphase.
In the G1 phase, the cell grows and performs normal functions while preparing for DNA replication. This phase is critical for cell growth and organelle production.
In the S phase, DNA replication occurs, resulting in the duplication of the cell's genetic material to ensure each daughter cell receives an identical copy.
In the G2 phase, the cell continues to grow and prepares for mitosis by synthesizing proteins and organelles required for cell division. This phase ensures the cell is ready to enter the M phase.
