Normal cells grow and divide continuously.
In prophase of mitosis, chromosomes
form and the nuclear envelope disappears.
are pulled toward opposite ends of the cell.
chromosomes line up along the equator of the cell
chromosomes begin to decondense and the two new nuclei begin to form.
In metaphase of mitosis, chromosomes
form and the nuclear envelope disappears.
are pulled toward opposite ends of the cell.
chromosomes line up along the equator of the cell
