Guida verificata passo dopo passo1
Understand the stages of mitosis: Prophase, Metaphase, Anaphase, and Telophase, and what occurs in each stage.
In Prophase, chromosomes condense and become visible, and the nuclear envelope begins to disintegrate.
In Metaphase, chromosomes align at the cell's equatorial plane, but the nuclear envelope has already disappeared by this stage.
In Anaphase, sister chromatids are pulled apart toward opposite poles of the cell.
In Telophase, chromosomes de-condense, and the nuclear envelope re-forms around each set of chromosomes.
