Cell Cycle
The cell cycle is the series of events that cells go through as they grow and divide. It’s crucial for cell growth, development, and repair. The cycle is divided into several phases:

Interphase: This is the longest phase and includes three sub-stages:
G1 Phase (Gap 1): The cell grows and performs its normal functions. It also prepares for DNA replication.
S Phase (Synthesis): DNA replication occurs, resulting in two identical sets of chromosomes.
G2 Phase (Gap 2): The cell continues to grow and prepares for mitosis. It checks for any errors in DNA replication and makes necessary repairs.
Mitosis: This is the process of cell division and is divided into several stages:
Prophase: Chromosomes condense and become visible, the nuclear envelope breaks down, and the mitotic spindle begins to form.
Metaphase: Chromosomes line up along the metaphase plate (the cell's equator).
Anaphase: Chromosomes are pulled apart to opposite sides of the cell.
Telophase: The nuclear envelope re-forms around each set of chromosomes, which begin to de-condense.
Cytokinesis: This is the final step where the cytoplasm of the cell divides, resulting in two separate daughter cells.
