During which stage of mitosis does the nucleus break down?
The breakdown of the nucleus occurs in the prophase stage of mitosis. This is when the nuclear envelope disintegrates, allowing the chromosomes to be released into the cytoplasm for subsequent division.
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 phase of mitosis spindle fibers disappear and new nucleus form at each end?
The phase of mitosis that the nucleus forms is the prophase phase.
What are four phases of nuclear division?
The stages of an induced nuclear fission are:capture of an incident neutron forming a compound nucleussplitting of the compound nucleus into two (or less frequently three) fragments plus 2-3 neutrons plus energy and radiation release due to mass deficit.The released nuclear energy is manifested as heat energy
Why does nucleolus disappear during pro-phase of mitosis and what is the mechanism of dissapearence?
The nucleolus disappears during prophase of mitosis because it is the stage where the nuclear envelope breaks down, causing the nucleolus to disperse. This disappearance is due to the disassembly of the nucleolar components and the redistribution of its content throughout the cell.
When does the nucleus reappear?
False, No it is the only phase where it disappears. It directly says it comes back in telophase but may be present during all other phases EXEPT prophase.
What structure within the nucleus disappears during prophase?
The nuclear envelope.
What order does the mitosis stage occur in?
ProphaseMetaphaseAnaphaseTelophaseSometimes, people will include a fifth event, called prometaphse, where the nuclear envelope disappears and the spindles form. Generally, this phase is classified with prophase.

How one division of the nucleus a new spindle forms around each group of chromosomes?
telophase
What structure within the nucleus becomes indistinct and finally disappears as the cell progresses through prophase?
nucleolus

Why does the nucleus disappear?
The nucleus of a cell disappears during mitosis, specifically during prophase, when the nuclear envelope breaks down. This allows the chromatin to condense into distinct chromosomes, facilitating their separation. The disappearance of the nucleus is essential for the accurate distribution of genetic material to the daughter cells during cell division. After mitosis, a new nuclear envelope forms around the separated chromosomes in the daughter cells during telophase.
What process needs to be undone when telophase occurs?
During telophase, nuclear division and cytokinesis need to be undone. This means the two daughter nuclei formed during telophase need to go back to a single, diploid nucleus and any division of the cytoplasm during cytokinesis needs to be reversed.
