In mitosis, the nuclear membranes form around the chromosomes at the telophase.
The nuclear membrane reforms around the nucleus during Telophase, the last phase of mitosis.
The phase of mitosis that begins when the nuclear membrane starts to fade is called prometaphase. During prometaphase, the nuclear membrane breaks down, allowing the spindle fibers to attach to the 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.
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 second phase of mitosis is called prophase. During prophase, chromosomes condense and become visible as distinct structures. In addition, the nuclear membrane starts to break down, allowing the chromosomes to move freely within the cell.

Prophase
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 re-forms during the telophase stage of mitosis. After the chromosomes have been pulled to opposite poles of the cell during anaphase, telophase sees the chromosomes begin to de-condense back into chromatin. The nuclear envelope then re-establishes around each set of chromosomes, resulting in two distinct nuclei in the newly forming daughter cells.
The second phase of mitosis is called prophase. During prophase, chromosomes condense and become visible as distinct structures. In addition, the nuclear membrane starts to break down, allowing the chromosomes to move freely within the cell.
During telophase of mitosis, a new nuclear membrane is forming around the separated daughter chromosomes. This process helps establish two distinct nuclei within the newly divided cells.
"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 nuclear membrane is reformed during the telophase stage of mitosis or meiosis. This process involves the reassembly of the nuclear envelope around the separated daughter chromosomes to form two distinct nuclei in each daughter cell.
That is telophase, the final stage of mitosis in which a new nuclear membrane forms around each set of daughter chromosomes and the chromosomes become less tightly coiled as they prepare to resume interphase.
