To accurately show a cell progressing through mitosis, the model should include the following key stages:
1. Prophase: The chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.
2. Metaphase: Chromosomes align at the cell's equator (metaphase plate) and are attached to spindle fibers at their centromeres.
3. Anaphase: Sister chromatids separate and move towards opposite poles of the cell.
4. Telophase: Chromosomes reach the poles, the nuclear envelope reforms around each set of chromosomes, and the spindle fibers disassemble.
5. Cytokinesis: The cytoplasm divides, resulting in two daughter cells.
When evaluating the models provided (A, B, C, D), look for the representation that accurately depicts these stages in sequence. Pay attention to the arrangement of chromosomes, spindle fibers, and the overall progression of the cell through mitosis. Choose the model that best illustrates the step-by-step process of cell division in an orderly and correct manner.
