Verified step by step guidance
1
Understand the process of mitosis, which is the division of a single cell into two identical daughter cells. Mitosis consists of several phases: prophase, metaphase, anaphase, and telophase.
Recognize that during prophase, the chromatin condenses into visible chromosomes, and the mitotic spindle begins to form.
Identify that during metaphase, the chromosomes align at the cell's equatorial plane, preparing for separation.
Note that during anaphase, the sister chromatids are pulled apart toward opposite poles of the cell.
Learn that during telophase, the cell begins to pinch in at the middle, forming a cleavage furrow, as the nuclear membranes start to reform around the separated sets of chromosomes, leading to the completion of cell division.
