The correct Answer is:
To determine the correct sequence of different phases of mitosis, we need to understand the stages involved in the process. Mitosis is a type of cell division that results in two identical daughter cells. It consists of several distinct phases, which occur in a specific order. Here is the step-by-step solution: ### Step-by-Step Solution: 1. **Interphase**: - Before mitosis begins, the cell is in interphase, which is not a part of mitosis but is crucial for preparing the cell for division. Interphase consists of three sub-phases: G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis). 2. **Prophase**: - The first phase of mitosis is prophase. During this phase, the chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down. The spindle fibers start to form from the centrosomes. 3. **Metaphase**: - Following prophase is metaphase. In this phase, the chromosomes align at the metaphase plate (the cell's equatorial plane), and spindle fibers attach to the centromeres of the chromosomes. 4. **Anaphase**: - The next phase is anaphase. Here, the centromeres split, and the sister chromatids are pulled apart towards opposite poles of the cell by the spindle fibers. 5. **Telophase**: - The final phase of mitosis is telophase. In this phase, the chromosomes reach the opposite poles of the cell, begin to decondense back into chromatin, and the nuclear envelope reforms around each set of chromosomes. 6. **Cytokinesis**: - Although not a phase of mitosis itself, cytokinesis often occurs concurrently with telophase, resulting in the division of the cytoplasm and the formation of two separate daughter cells. ### Correct Sequence of Mitosis: The correct sequence of the phases of mitosis is: 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase ### Final Answer: The correct sequence of different phases of mitosis is: **Prophase → Metaphase → Anaphase → Telophase**. ---
