Meiosis is divided into meiosis I and meiosis II. Like mitosis, the onset of meiosis I is preceded by all 46 of a cell's chromosomes replicating. In meiosis, however, after the nuclear membrane is dissolved in prophase, the homologous chromosomes pair off, side by side, with the homolog d...
Mitosis and meiosis are both processes of cell division, but they differ in terms of the number of daughter cells that are...
Telophase is the final phase of mitosis, and this is when the official division of one cell into two happens. First, the chromosomes relax back into chromatin and a nuclear envelope forms around each chromatin blob, making it into a brand new nucleus. A nucleolus appears in each of these n...
Answer to: (a) What role do meiosis and mitosis play in maintaining the integrity of the genetic code during cloning? (b) What role do they play in...
During prophase I of meiosis I, a process called recombination can occur. This process is used to create variation and is absent in the process of mitosis. The process of meiosis is something that only occurs in organisms that reproduce sexually. Mitosis occurs in all types of organisms.Answe...
What would happen if gametes were produced by mitosis instead of meiosis? Describe what happens to the chromosomes in the following stage of Mitosis: Cytokinesis. What is cytokinesis and when does it occur? What basically happens during prophase, metaphase, anaphase, and telophase? Explain what hap...
What happens to chromosomes during meiosis? What's the difference between metaphase 1 and 2? Describe what happens to chromosomes before mitosis. What happens during synapsis in meiosis? What happens to the chromosome number during meiosis? What would happen if synapsis did not occur in meiosis?
The function of the centromere is primarily to ensure the correct distribution of chromosomes to daughter cells during mitosis and meiosis, thereby maintaining genetic stability. In contrast, the centrosome plays a broader role in cell organization, not only participating in chromosome segregation but al...
Nondisjunction may occur whenever a cell divides its chromosomes. This happens during normal cell division (mitosis) and gamete production (meiosis). Mitosis DNA replicates prior to cell division. The chromosomes line up in the middle plane of the cell during metaphase and the kinetochores of sister...
What parts of plants are most impacted by mitosis? What are the two mechanisms of variation in Meiosis, and during which stage(s) does each occur? Explain how cells regulate the process of mitosis. How does mitosis work? What is the function of mitosis in the cell?
