During the phase of mitosis when the chromosomes align at the middle part of the cell, it is called metaphase.
During the process of mitosis, the alignment of the chromosomes occurs during the metaphase phase. To determine the correct answer, we need to understand the different phases of mitosis and their characteristics:
1. Prophase: During prophase, the nucleus starts to break down, and the chromosomes condense and become visible. Spindle fibers also begin to form.
2. Metaphase: In metaphase, the chromosomes align at the middle part of the cell, known as the metaphase plate. This alignment is crucial for the equal separation of genetic material during cell division.
3. Anaphase: Anaphase is the phase where the sister chromatids separate and move towards opposite poles of the cell. This separation is facilitated by the shortening of the spindle fibers.
4. Telophase: During telophase, the nuclear envelope reforms around the separated chromosomes, forming two distinct daughter nuclei. The chromatin also starts to decondense, and cytokinesis, where the cell actually divides, begins.
Therefore, the correct answer is metaphase.
