Cell Cycle

Short Definition

Cell cycle is the series of events that a cell goes through from its formation to its division into two daughter cells.

Detailed Explanation

The cell cycle regulates growth, DNA replication, and cell division. It ensures proper distribution of genetic material to daughter cells. It has several phases that prepare the cell for division and growth.

Phases of Cell Cycle

• Interphase: Cell grows, replicates DNA, and prepares for division (G1, S, G2 phases).
• Mitosis: Division of nucleus (prophase, metaphase, anaphase, telophase).
• Cytokinesis: Division of cytoplasm forming two daughter cells.

Importance

The cell cycle is essential for growth, tissue repair, and reproduction in organisms. Proper regulation prevents mutations and diseases like cancer.
