stage of mitosis when nuclear envelop disappears and the chromosomes form is the "PROPHASE"
This is related to mitosis. Once the chromosomes are fully condensed, the nuclear envelop is disolved in order to let the mitotic spindle is put in it's place to migrate the chromatids to the poles. Once the chromatids have already migrated, the cytokinesis process take place, dividing the cell into two daughter cells that eventually rebuild their nuclear envelop.
"scientist have not discovered WHY it happens"It does not matter if scientists have discovered it or not, but the nuclear membrane disappears during PROPHASEHope this helped!!!
The stage of mitosis where chromosomes shorten and thicken and the nuclear membrane begins to disappear is prophase. During prophase, the chromatin condenses into distinct chromosomes and the nuclear envelope breaks down, allowing the chromosomes to interact with the spindle fibers.
The nuclear membrane disappears during prophase of mitosis. This allows the chromosomes to be condensed and move freely within the cell. At the end of mitosis, during telophase, the nuclear membrane reforms around the separated chromosomes.
This process occurs during mitosis in eukaryotic cells. As the cell prepares to divide, the nucleolus, which is responsible for producing ribosomes, disappears. Additionally, the nuclear envelope breaks down to allow the chromosomes to separate into two daughter cells.

In eukaryotic cells chromosomes are found within the nucleus. The only exception to this is during mitosis (i.e. cell division) when the nuclear membrane disappears and the chromosomes line up at the metaphase plate and then move towards opposite direction in anaphase. Reaching the telophase these are again surrounded by the nuclear envelop.

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.
Disappears in prophase and reappears in telophase.
The nuclear envelope disappears during the prophase stage of mitosis. This allows the chromosomes to be free within the cell and facilitates their separation and movement during cell division.
The phase where two new nuclear envelopes form around the two sets of daughter chromosomes is called telophase. In telophase, the nuclear membrane reforms around the chromosomes and the nucleoli reappear. This marks the end of nuclear division in cell mitosis.
The first step in mitosis is the prophase stage, where chromatin condenses into chromosomes and the nuclear envelope breaks down. This is followed by the prometaphase stage, where spindle fibers attach to the chromosomes at the kinetochore.
