Guida verificata passo dopo passo1
Understand the process of mitosis, which is the division of a single cell into two genetically identical daughter cells. Mitosis consists of several phases: prophase, metaphase, anaphase, and telophase.
Recall that during prophase, the chromatin condenses into visible chromosomes, and the mitotic spindle begins to form. The nuclear envelope starts to break down.
In metaphase, the chromosomes align at the equatorial plane of the cell, known as the metaphase plate. This alignment ensures that each daughter cell will receive one copy of each chromosome.
During anaphase, the sister chromatids are pulled apart by the spindle fibers toward opposite poles of the cell.
Finally, in telophase, the chromosomes arrive at the poles, and the nuclear envelope re-forms around each set of chromosomes, completing the process of mitosis.
