During prometaphase, the nuclear envelope fragments and the spindle microtubules are able to reach the chromosomes.
Each of the two chromatids of each chromosome, at this point, has a kinetochore.
The microtubules attach to the kinetochores, forming "kinetochore microtubules" which basically jerk the chromosomes back and forth.
No, prometaphase is a stage in mitosis, not meiosis. In meiosis, there is a prophase I stage that is similar to prometaphase in mitosis.
Mitosis has six different phases in the cell division cycle including intraphase, prophase, prometaphase, metaphase, anaphase and telophase. Prometaphase occurs right after the end of prophase.
Prophase Prometaphase Metaphase Anaphase Telophase ( containing cytokenesis )
The phases of Mitosis are Interphase, Prophase, Metaphase, Anaphase, Telophase (IPMAT). Cytokiensis is a separate thing altogether from Mitosis. So anything other than IPMAT is "not a phase in mitosis".
The subphases are: G1 phase, S phase, and G2 phase. The convention phases are: prophase, prometaphase, metaphase, anaphase, and telophase.

Answerlate prophase (aka prometaphase)
The phase of mitosis that begins when the nuclear membrane starts to fade is called prometaphase. During prometaphase, the nuclear membrane breaks down, allowing the spindle fibers to attach to the chromosomes.
The stages of Mitosis are are interphase, prophase, prometaphase, metaphase, anaphase, and telophase.

There is no stage between metaphase and anaphase. Mitosis has four stages, first its prophase then metaphase then anaphase then 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!!!
Mitosis typically consists of five distinct stages: prophase, prometaphase, metaphase, anaphase, and telophase. Each stage involves specific processes and activities that contribute to the overall division of the cell into two identical daughter cells.
1 splits in two
There is not a particular "cell" that breaks down the nucleus during the cell process of mitosis. However, the nucleus does begin to break down in the phase known as prophase/prometaphase.
