Study Notes
Cell Growth and Repair
- Mitosis plays a crucial role in cell growth and repair by producing new cells.
Phases of Mitosis
- Mitosis consists of four main phases: prophase, metaphase, anaphase, and telophase, which must occur in sequence.
Prophase
- During prophase, chromosomes become visible as they condense, marking the beginning of mitosis.
Metaphase
- In metaphase, chromosomes align at the cell's equatorial plane, preparing for separation.
Spindle Fibers
- Spindle fibers are essential structures that facilitate the movement of chromosomes by pulling them apart during mitosis.
Interphase
- Interphase is the preparatory stage of the cell cycle where DNA replication occurs, setting the stage for mitosis.
Anaphase
- Anaphase is characterized by the action of spindle fibers pulling sister chromatids toward opposite poles of the cell.
Chromosome Count in Human Cells
- Each human cell contains 23 pairs of chromosomes, resulting in a total of 46 chromosomes post-mitosis in daughter cells.
Non-Stage of Mitosis
- "Diphase" is not a recognized phase of mitosis, highlighting common misconceptions regarding the mitotic process.
Cancer
- Cancer is a disorder marked by the uncontrolled replication and division of cells due to failures in mitotic regulation.
Interphase Characteristics
- A statement claiming that cells in interphase have condensed chromosomes is false, as chromosomes are typically de-condensed during this phase.
Mitosis and the Cell Cycle
- Mitosis constitutes only a small fraction of the entire cell cycle, emphasizing the importance of interphase for cell preparation and functionality.
