The phase of mitosis during which the chromosomes align at the middle part of the cell is the metaphase.
The phase of mitosis during which the chromosomes align at the middle part of the cell is called metaphase. To determine the correct answer, you can recall the different phases of mitosis and their distinct characteristics.
Firstly, prophase is the initial phase of mitosis, during which the chromosomes condense and become visible. The nuclear membrane also begins to break down.
Anaphase is the phase during which the paired chromosomes separate and move towards opposite ends of the cell. The spindle fibers help in pulling the chromosomes apart.
Telophase, on the other hand, is the final phase of mitosis, characterized by the formation of a nuclear membrane around the separated chromosomes. The chromosomes begin to unwind, and the cell begins to prepare for cytokinesis (cell division).
Finally, metaphase is the phase in which the chromosomes line up along the middle of the cell, forming a single plane called the metaphase plate. This alignment is crucial for the equal distribution of genetic material to the daughter cells.
In this case, the correct answer is metaphase.
