telophase
Telophase, where chromosomes uncoil, spindles disappear, nucleolus and nuclear envelope reappears.
The four stages of Mitosis is: Prophase: 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. Metaphase:the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle fibers Anaphase:The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle fiber. Telophase: The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.
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.
Prophase
In the cell cycle, the nuclear envelope reforms around each cluster of chromosomes in telophase.
The nuclear membrane reforms around the nucleus during Telophase, the last phase of mitosis.
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.

The Nuclear envelope
It does right after mitosis.
Open mitosis occurs in most animal cells where the nuclear envelope breaks down ("opens" before the chromosomes separate. Closed mitosis occurs in some fungi, such as Aspergillusand Saccharomycesspecies, where the chromosomes divide within an intact ("closed") cell nucleus.
In prophase stage, the replicated chromosomes condense and the nuclear envelope disappears. Earlier in prophase, chromatin visible condenses into the chromosomes.
The following process happens in the prophase of mitosis, during which the nuclear envelope will disappear along with the nucleolus. The chromosomes are then ready to be moved to the center to be split.
stage of mitosis when nuclear envelop disappears and the chromosomes form is the "PROPHASE"
