Cell Cycle And Mitosis – FAQ
The cell cycle is a series of events that cells go through as they grow and divide. It is composed of four main phases: G1 (growth), S (DNA synthesis), G2 (preparation for mitosis), and M (mitosis or cell division). This cycle ensures that cells duplicate accurately and function correctly.
Mitosis is crucial because it allows for growth and repair in multicellular organisms. It ensures that each daughter cell receives an identical set of chromosomes, maintaining genetic consistency across cells. Without mitosis, organisms would not be able to develop, grow, or heal wounds effectively.
Mitosis consists of five stages: prophase, metaphase, anaphase, telophase, and cytokinesis. During prophase, chromosomes condense and the nuclear membrane breaks down. Metaphase aligns chromosomes in the middle of the cell. Anaphase separates sister chromatids to opposite poles. Telophase reforms the nuclear membrane around each set of chromosomes. Finally, cytokinesis divides the cytoplasm, resulting in two identical cells.
The cell cycle is regulated by checkpoints that ensure each phase is completed correctly before moving on to the next one. Key checkpoints occur at the G1, G2, and M phases. These checkpoints assess factors such as DNA integrity and cell size, preventing errors in cell division and reducing the risk of mutations.
Errors in the cell cycle can lead to uncontrolled cell division, which may result in cancer. If checkpoints fail to detect and repair these errors, damaged DNA can be passed on to daughter cells. This can cause genetic mutations and disrupt normal cell function, posing serious health risks.
