During the interphase
Prophase
cytokinesis
Nuclear membrane and nucleolus
Before the nuclear envelope of a cell breaks down during the mitosis process, the DNA has to be duplicated. After the envelope dissolves, the chromosomes separate, then the cell finally splits.
During prophase, the first stage of mitosis, the chromosomes become visible as distinct structures. The nuclear envelope also now breaks down, and a spindle forms.
an interphase is the stage of a cell between two successive mitotic or meiotic divisions an a prophase is the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes.
Enzymes
the nuclear envelope breaks down during prophase near the same time the chromatin condenses.
If the nuclear envelope didn't break down, the spindle would not attach to the kinetochore proteins on the condensed chromosomes in prometaphase because the nuclear envelope would be in the way.
To be or not to be, that is the question.
Answerlate prophase (aka prometaphase)
during prophase, in order to allow microtubules to attach to the duplicated chromosomes

Before the nuclear envelope of a cell breaks down during the mitosis process, the DNA has to be duplicated. After the envelope dissolves, the chromosomes separate, then the cell finally splits.
During prophase, the first stage of mitosis, the chromosomes become visible as distinct structures. The nuclear envelope also now breaks down, and a spindle forms.
The second stage of the mitotic phase, called metaphase, overlaps with the first stage, called prophase, in terms of time. This means that while one cell is going through metaphase, another cell in the same population may be in prophase. However, the events that occur in these two stages are distinct. In prophase, chromosomes condense and the nuclear envelope breaks down, while in metaphase, the condensed chromosomes align at the center of the cell.
