It is Telephase because in Anaphase the centromeres split, and the sister chromatids are pilled to the opposite poles of the cell by the spindle fibers. In Cytokinesis it is already split and it made two identical nuclei.
The nuclear membrane reforms around the nucleus during Telophase, the last phase of mitosis.
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.
At M (Mitosis) Phase, where all of the Kinase [turn -on and -off] enzymes {that determine wether or not the multitudinous 'nuclear-membrane components' are set to associate or not} are set to OFF, all of these nuclear-membrane-components just simply vanish into the aqueous ' fluids ' [that is the Cytoplasm] that are then simply shared between the daughter cells. When the new daughter cell 'sets up housekeeping' her first task is to reestablish the nuclear membrane. By the re-enabling of the " Kinase = On " system, the nuclear membrane and ALL OF ITS COMPONENTS will then just simply reappear and 'automatically' resemble to form the nuclear envelope.
During telophase of mitosis or meiosis, a new nuclear membrane forms around the separated sister chromatids or the daughter chromosomes. This process helps to re-establish separate nuclear compartments and protect the genetic material within each daughter cell. The nuclear membrane is derived from the endoplasmic reticulum and surrounds the chromosomes, providing a barrier between the nucleus and the cytoplasm.

The phase of mitosis that the nucleus forms is the prophase phase.
The development of a new nuclear membrane occurs in three main phases: first, during telophase, the nuclear envelope begins to reassemble around the separated sets of chromosomes. Second, the membranes of the endoplasmic reticulum (ER) merge and reform around these chromosomal regions. Finally, during cytokinesis, the nuclear envelope fully matures, encapsulating the nuclei of the daughter cells, thus completing cell division.
The nuclear membrane breaks down during prophase, while the Deoxyribonucleic Acid (DNA) The nuclear membrane must break down to allow the chromosomes to be pulled apart and away from the area of the former nucleus towards the pole where the daughter cell will be formed. If the nuclear membrane did not break down the spindle fibers would not be able to reach the chromosomes and they would not be moved towards opposite poles of the cell.
yes, new ones of new designs.
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.
New nuclear membranes are completed during the telophase phase of mitosis. In this phase, the separated chromosomes reach the opposite poles of the cell, and the nuclear envelope reforms around each set of chromosomes, creating two distinct nuclei. This marks the final stage of cell division before the cytoplasm divides in cytokinesis.
The phase of mitosis that has no clear nucleus is called prometaphase. In this phase, the nuclear envelope breaks down, allowing the chromosomes to become more condensed and visible, but the formation of the new nuclear envelope has not yet occurred.
