Study Notes
Mitosis
- Purpose is to create somatic (body) cells.
- Involves one round of cell division.
- Produces two identical somatic cells at the end.
- Sister chromatids are formed by duplicating a single chromosome.
Phases of Mitosis
- Prophase: Nucleus disappears; centrioles form and move to opposite poles.
- Metaphase: Chromosomes align at the cell's equator; spindle fibers attach to centromeres.
- Anaphase: Sister chromatids are separated and pulled to opposite sides of the cell.
- Telophase: Cleavage furrow appears; chromatids reach opposite poles.
Additional Details
- Cytokinesis, the division of the cytoplasm, is not part of mitosis but follows it.
- In cytokinesis, the cytoplasm divides, resulting in the formation of two daughter cells.
Meiosis
- Purpose is to produce sex cells (gametes).
- Involves two rounds of cell division.
- Results in four non-identical sex cells (haploid).
Phases of Meiosis
- Prophase I: Diploid chromosomes exist in pairs; crossing over occurs, enhancing genetic diversity.
- Metaphase I: Diploid pairs line up at the equator of the cell.
- Prophase II: Haploid chromosomes, each consisting of two chromatids, are present.
- Metaphase II: Haploid chromosomes align at the equator.
- Telophase I: Nuclear membrane reforms around pairs of chromatids.
- Telophase II: Nuclear membranes reform, resulting in haploid cells with single chromatids.
Consequences of Inhibiting Cell Division
- If a chemical halts cell division, it results in cell death and prevents reproduction, causing potential damage to tissues and organs.
