What phase of mitosis does the nuclear envelope and the nucleus disappear and a spindle forms?

The phase of mitosis where the nuclear envelope and nucleus disappear is called prophase. During prophase, the chromatin condenses into discrete chromosomes, and the spindle apparatus begins to form, facilitating the movement of chromosomes during cell division.


What is the phase in mitosis where the nuclear membrane disappears?

"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!!!


What phase of mitosis is essentially the opposite of pro-phase in terms of nuclear changes?

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 Enevlope Begins To Disappear?

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.


What phase does the nuclear envelope reform?

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.

What phase does the nuclear envelope disappear and spindles are formed.?

Prophase.


What phase does the nucleus and nucleus disappear?

The phase where the nucleus and the nuclear membrane disappear is called prometaphase. This is the phase following prophase in mitosis or meiosis when the nuclear envelope breaks down and the chromosomes become more condensed and visible.


In what phase does the spindles disappear?

Spindles disappear during telophase, which is the final phase of mitosis. In this phase, the chromosomes reach the opposite poles of the cell, and the spindle fibers break down and disappear. This is followed by the reformation of the nuclear envelope around the separated sets of chromosomes, leading to the completion of cell division.


In what phase nuclear membrane reforms and chromosomes disappear?

The nuclear membrane reforms and chromosomes disappear during the telophase phase of mitosis. In this phase, the separated sister chromatids reach the opposite poles of the cell, and the nuclear envelope begins to reassemble around each set of chromosomes. Subsequently, the chromosomes decondense back into chromatin, preparing for the next cell cycle.

What phase is the nuclear membrane is still visible?

During prometaphase, the nuclear envelope (membrane) breaks apart. However, some fragments of the nuclear envelope are still visible.

The phase of cell division in which the nuclear envelope and nucleolus are disappearing?

prophase


In what phase does the nucleus disappear?

The nucleus disappears during prophase of mitosis. In this phase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the microtubules to access the chromosomes. This dissolution of the nucleus is crucial for the subsequent steps of cell division.
