The cell life cycle is the series of events that cells go through as they grow and divide. This fundamental process is essential for organism development, tissue repair, and reproduction. The cycle involves continuous phases of cell growth, DNA replication, and division into two daughter cells, forming a continuous loop that sustains all life.
Interphase is the longest phase of the cell cycle, occupying approximately ninety percent of the total cycle duration. During this crucial preparation phase, cells grow significantly in size and accumulate the materials and energy needed for successful division. The cell duplicates its organelles, prepares for DNA replication, and maintains normal metabolic activities. This extended period ensures that cells are fully prepared before entering the dramatic mitotic phase.
