Study Notes
Mitosis Stages
- Prophase: Chromatin condenses into visible chromosomes; nuclear envelope breaks down; spindle fibers form from centrioles.
- Metaphase: Chromosomes align at the cell's equatorial plane, attached to spindle fibers at their centromeres.
- Anaphase: Sister chromatids are pulled apart towards opposite poles of the cell, ensuring each daughter cell will receive an identical set of chromosomes.
- Telophase: Chromatids reach the poles and decondense back into chromatin; nuclear envelopes reform around each set of chromosomes.
Cell Cycle Components
- Interphase: The phase where the cell grows, duplicates its DNA, and prepares for mitosis; consists of G1, S, and G2 phases.
- Chromosome: A structure made of DNA and protein that carries genetic information; each chromosome consists of two sister chromatids during mitosis.
- Spindle Fibers: Protein structures that segregate chromosomes during cell division; they extend from centrioles to the centromeres of chromosomes.
- Chromatids: Identical halves of a duplicated chromosome (sister chromatids) that separate during anaphase.
- Daughter Cells: The two new cells that result after cytokinesis, each with a complete set of chromosomes.
- Chromatin: The relaxed form of DNA, which is not yet condensed into chromosomes; exists during interphase.
- Cell Membrane: The protective barrier of the cell that regulates what enters and exits; plays a role in maintaining homeostasis.
- Nucleus: The membrane-bound organelle that houses genetic material (DNA) and coordinates cell activities.
- Centriole: A cylindrical structure involved in the formation of spindle fibers during cell division.
- Nuclear Membrane: The double lipid bilayer that encloses the nucleus, regulating the flow of materials in and out of the nucleus.
