The cell cycle: a molecular approach

The cell cycle is the process cells go through to grow, duplicate their DNA, and divide into new cells. It has several stages: in interphase, the cell prepares by copying DNA; during mitosis, the copied DNA is evenly distributed into two new cells. This cycle ensures proper growth, repair, and maintenance of tissues. Molecularly, it involves proteins and checkpoints that regulate and ensure everything proceeds correctly. Overall, the cell cycle is essential for life, enabling organisms to develop, heal, and reproduce cellularly.
