Study Notes
Cell Cycle Phases
The cell cycle is the series of events that occur in a cell leading up to its division into two genetically identical daughter cells. The cell cycle can be divided into three main stages: interphase, mitosis, and cytokinesis.
Interphase
Interphase is the longest stage of the cell cycle, which lasts for approximately 20 hours in mammalian cells. It is divided into three subphases: prophase, metaphase, and anaphase, which are collectively known as mitosis.
Prophase
During prophase, the chromatin condenses into chromosomes, the nuclear envelope begins to break down, and the mitotic spindle begins to form.
Metaphase
In metaphase, the chromosomes align at the metaphase plate, which is the equatorial plane of the cell.
Anaphase
Anaphase is the stage where sister chromatids are separated and pulled to opposite ends of the cell by the mitotic spindle.
Mitosis
Mitosis is the stage where the chromosomes are separated, and each chromosome forms a new nucleus in each daughter cell. It is further divided into prophase, metaphase, anaphase, and telophase.
Prophase
During prophase, the chromatin condenses into chromosomes, the nuclear envelope begins to break down, and the mitotic spindle begins to form.
Metaphase
In metaphase, the chromosomes align at the metaphase plate, which is the equatorial plane of the cell.
Anaphase
Anaphase is the stage where sister chromatids are separated and pulled to opposite ends of the cell by the mitotic spindle.
Telophase
Telophase is the stage where the chromosomes reach the opposite ends of the cell, a new nuclear envelope forms around each set of chromosomes, and the chromatin begins to decondense.
Cytokinesis
Cytokinesis is the stage where the cytoplasm divides, forming two separate daughter cells. It is the final stage of the cell cycle, leading to the formation of two genetically identical daughter cells.
In summary, the cell cycle consists of three main stages: interphase, mitosis, and cytokinesis. Interphase is the longest stage, followed by mitosis, where the chromosomes are separated, and cytokinesis, where the cytoplasm divides, leading to the formation of two genetically identical daughter cells.
Test your knowledge about the stages of the cell cycle, including interphase, mitosis, and cytokinesis. Learn about the key events that occur during each phase such as chromatin condensation, chromosome alignment, and cytoplasm division.
