Interphase
During prometaphase, the nuclear envelope (membrane) breaks apart. However, some fragments of the nuclear envelope are still visible.
The nuclear envelope reforms and the nucleoli reappear during telophase of mitosis. This phase marks the end of nuclear division as the newly formed daughter nuclei begin to re-establish their nuclear envelopes.
The phase of mitosis that is essentially the opposite of prophase in terms of nuclear changes is telophase. During telophase, the nuclear envelope reforms around the separated daughter chromosomes, leading to the formation of two distinct nuclei. In contrast, during prophase, the nuclear envelope breaks down to allow for chromosome condensation and rearrangement.
The nuclear envelope reforms during telophase, which is the final stage of mitosis. In telophase, the nuclear membrane and nucleolus reappear, and the chromosomes begin to decondense back into chromatin.
in what phase nuclear envelopes are absent?
The nuclear membrane begins to fade during the prophase stage of mitosis, which is the phase in the cell cycle when the chromatin condenses into chromosomes and the nuclear envelope breaks down. This allows the chromosomes to be better organized for separation during cell division.
The nuclear membranes are present during the interphase and the prophase of mitosis. During interphase, the nuclear envelope surrounds the nucleus, protecting the genetic material. In prophase, the nuclear membrane begins to break down as the cell prepares for division. After this phase, the nuclear envelope re-forms during telophase.
The nuclear envelope and nucleolus are broken down and absorbed during the prophase of mitosis. This prepares the cell for the division of its genetic material.
Prophase.
"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!!!
prophase
The events of prophase in mitosis, such as condensation of chromosomes and breakdown of the nuclear envelope, are opposite to those that occur during telophase, where chromosomes decondense, and the nuclear envelope reforms.
