What happens during prophase of mitosis?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

Front

What occurs during metaphase of mitosis?

Back

During metaphase, chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes.

Front

What is anaphase in mitosis?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite poles of the cell.

What happens during telophase of mitosis?

Back

During telophase, two new nuclei form around the separated sets of chromosomes, and the chromosomes begin to de-condense.

Why do stomach cells and skin cells function differently?

Back

Stomach cells and skin cells function differently because they use different genes in the DNA, despite having the same DNA.
