=In this stage the nuclear envelope breaks down so there is no longer a recognizable nucleus. Some mitotic spindle fibers elongate from the centrosomes and attach to kinetochores, protein bundles at the centromere region on the chromosomes where sister chromatids are joined. Other spindle fibers elongate but instead of attaching to chromosomes, overlap each other at the cell center.=

What does the correct chromosomal condition at prometaphase of mitosis look like?
The chromosomes during the prometaphase of mitotis in biology means that the chromosomes are gathered in the middle in a line with the spindles beginning to attach.
When the nucleus disappears during prophase it fragments into which fuse to reform the nucleus during telophase?
The nuclear envelope disappears during prometaphase.
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!!!
Do meisosis and mitosis have metaphase?
Mitosis for sure has metaphase. Scientists are guessing that meiosis has it too, but they combine it and make it "prometaphase," because prophase and metaphase happens so fast in meiosis.
Kinetochore-microtubule interactions move chromosomes to midline?
Prometaphase

Is prometaphase in meiosis?
Yes.

At prometaphase of mitosis?
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.
When does the spindle attach to the kinetochores?
Prometaphase
Which phase does the nuclear membrane disappears?
prometaphase
Do meisosis and mitosis have metaphase?
Mitosis for sure has metaphase. Scientists are guessing that meiosis has it too, but they combine it and make it "prometaphase," because prophase and metaphase happens so fast in meiosis.
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.
Kinetochore-microtubule interactions move chromosomes to midline?
Prometaphase
What is the phase of mitosis where the chromosomes lines at the center?
Prometaphase.
What disappears during prometaphase?
Telophase is the final stage of cell division. During telophase, the spindle fibers disappear due to the depolymerization of the microtubules.
