No. The nuclear envelope does not re-form until telophase.
During Telophase the nuclear envelope re-forms.
During mitosis, it is when the cell is in telophase.
During prophase the nuclear membrane disintegrates. The metaphase through anaphase the molecules are not formed as membranes. During telophase it reintegrates and in interphase it is present as normal.
During prometaphase, the nuclear envelope (membrane) breaks apart. However, some fragments of the nuclear envelope are still visible.
Cellular Division.
The cellular event that happens by removing the nuclear envelope is cell division. Cell division happens during Prophase.
The nuclear envelope reforms during Telophase.
telophase
"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 reforms around the nucleus during Telophase, the last phase of mitosis.
During mitosis, it is when the cell is in telophase.
Telophase is where the cell moves out of mitosis back into interphase. Cytokinesis occurs (if you don't count that as a separate phase); the nuclear membrane reforms; chromosomes return to chromatin; the spindle fibers dissolve and return to the cytoskeleton. It's very similar in meiosis.
During prophase the nuclear membrane disintegrates. The metaphase through anaphase the molecules are not formed as membranes. During telophase it reintegrates and in interphase it is present as normal.
anaphase
The Nuclear envelope
During meosis 2, there is a phase called telophase 2 where the nuclear envelop forms around the chromosomes of the haploid cells
Interphase
During prometaphase, the nuclear envelope (membrane) breaks apart. However, some fragments of the nuclear envelope are still visible.
