Cell Cycle & Mitosis

The cell cycle is the series of events that take place in a cell leading to its division and replication. It consists of interphase (G1, S, G2) and the mitotic phase (mitosis and cytokinesis).

The main phases of the cell cycle are Interphase (G1, S, G2) and the Mitotic phase (Mitosis and Cytokinesis).

During G1 phase, the cell grows and carries out normal functions, preparing for DNA replication.

During S phase, DNA replication occurs, resulting in two identical sets of chromosomes.

During G2 phase, the cell continues to grow and prepares for mitosis, including the synthesis of proteins necessary for cell division.

Mitosis is the process of nuclear division in eukaryotic cells that results in two identical daughter nuclei.

The stages of mitosis are prophase, metaphase, anaphase, and telophase.

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

During metaphase, chromosomes line up at the cell's equatorial plane, and spindle fibers attach to the centromeres.

During anaphase, sister chromatids are pulled apart to opposite poles of the cell as the spindle fibers shorten.
