Study Notes
Mitosis
- Purpose is to regenerate cells.
- Involves a single division of the cell.
- Results in the formation of diploid cells.
- Sister chromatids are two identical chromosomes that form during cell division.
- Prophase involves the formation of homologous pairs of chromosomes.
- During metaphase, chromosomes align at the cell's equator.
- Anaphase occurs when paired chromosomes are separated and pulled apart.
- Telophase involves the formation of the nuclear membrane, leading to two daughter cells.
- Cytokinesis is not a part of mitosis; it is a separate process that occurs after.
- During cytokinesis, a new double membrane forms, allowing the cytoplasm to divide.
Meiosis
- The purpose is to produce egg cells.
- Cells divide twice during meiosis.
- Final result is the formation of egg cells.
- Prophase I is characterized by chromosomes condensing and pairing, with the nuclear membrane breaking down.
- In metaphase I, chromosomes line up at the center and spindle fibers attach, whereas metaphase II has sister chromatids aligning along the center.
- Telophase I forms a membrane around each set of chromosomes and divides the cytoplasm, while telophase II forms membranes around each set of chromatids.
- In anaphase I, chromosomes separate and are drawn to opposite cell ends; in anaphase II, sister chromatids separate and move to opposite ends of the cells.
