FAQ
Q: What is mitosis?
A: Mitosis is the process of cell division where a single cell divides into two identical daughter cells.
Q: What is the main function of mitosis in cell growth and regeneration?
A: Mitosis is essential for growth, repair, and maintenance of multicellular organisms by producing new cells to replace old or damaged ones.
Q: How does mitosis differ from meiosis in cell division?
A: Mitosis results in two identical daughter cells with the same number of chromosomes as the parent cell, while meiosis produces four genetically diverse daughter cells with half the number of chromosomes.
Q: Can you explain the acronym PMAT in the context of mitosis?
A: PMAT stands for Prophase, Metaphase, Anaphase, and Telophase, which are the four main phases of mitosis where the cell undergoes nuclear division and cell division.
Q: What happens during Prophase in mitosis?
A: In Prophase, the chromatin condenses into visible chromosomes, the nuclear membrane breaks down, and spindle fibers begin to form.
Q: Describe the events that occur during Metaphase in mitosis.
A: During Metaphase, the chromosomes align at the cell's equator, and spindle fibers attach to the centromeres of each chromosome.
Q: What characterizes Anaphase in mitosis?
A: Anaphase is the phase where the sister chromatids of each chromosome are pulled apart towards opposite poles of the cell by the spindle fibers.
Q: What processes take place during Telophase of mitosis?
A: In Telophase, the chromosomes reach the opposite poles of the cell, the nuclear envelope reforms around each set of chromosomes, and the spindle fibers disintegrate.
