1. The cell cycle is a series of events that take place in a cell leading to its division and duplication.
2. It consists of four main phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis).
3. During the G1 phase, the cell grows and prepares for DNA replication.
4. In the S phase, DNA synthesis occurs, resulting in the duplication of the cell’s chromosomes.
5. The G2 phase involves further growth and preparation for mitosis, including the synthesis of proteins and organelles needed for division.
6. Mitosis (M phase) is the process where the nucleus divides, followed by cytokinesis, which divides the cytoplasm, resulting in two daughter cells.
7. Checkpoints regulate the cell cycle to ensure each phase is completed accurately before proceeding to the next.
8. The cell cycle is tightly controlled by regulatory proteins such as cyclins and cyclin-dependent kinases (CDKs).
9. Disruptions in the cell cycle can lead to uncontrolled cell division, which may result in cancer.
10. Understanding the cell cycle is crucial for developing treatments that target rapidly dividing cells, such as chemotherapy drugs.
