the first stage in mitosis is prophase, and in prophase the nuclear membrane fades and the chromosomes start to coil up. theyre scattered like x's in the mother cell and spindle fibers are forming as well. next is metaphase where the chromosomes go to the middle of the cell. then the chromosomes split up and slide on the fibers to the end to the end of the cell during anaphase. the final step is telophase and the chromosomes uncoil. the spindle disappears and the membrane nuclear forms around the two new nuclei.

∙ 15y agoInterphase - As the cell prepares for mitosis, the chromosomes replicate during the S phase of interphase.
Prophase - The replicated chromatids begin to coil into recognizable chromosomes; the nuclear membrane fragments; centrioles move to form the cell's poles; spindle fibers form; nucleolus disintegrates.
Metaphase - Chromosomes attach to spindle fibers at their centromeres and then move to the equator.
Anaphase - Chromatids, now called daughter chromosomes, separate toward the poles.
Telophase - The nuclear membranes and nucleoli re-form; spindle fibers fragment; the chromosomes unwind and change from chromosomes to chromatin.
Daughter Cells: Cytokinesis occurs and two daughter cells are formed from the dividing cells.

Metaphase- Chromosomes line up at equator of cell
Anaphase- Chromosomes move to opposite sides of the cell
Telophase- nuclear envelopes reform around each new daughter nuclei.

Sorry, 1Jazz, but prometaphase is now a phase. Nuclear envelope completes it's disintegration and microtubles attach to and begin to move chromosome to metaphase plate. Otherwise good explanations.

∙ 15y agoBriefly:
1. In prophase, the chromosomes appear as DNA condenses; the nuclear envelope breaks down; the centriole divides (if there is one, and if it hasn't already divided in the G1 phase).
2: Metaphase: The mitotic spindle forms, as the tractor fibers drag the chromosomes into the equatorial plane between the two centrioles on the poles.
3. In anaphase, the tractor fibers shorten, separating the chromosomes into 2 identical sister chromatids. These chromatids then migrate to opposite poles, near the origins of the spindle.
4. In telophase, nuclei form around the chromatids, DNA structure loosens, and cytokinesis takes place (the cell actually splits into two).

Are the stages of mitosis occurs simultaneously on a meristem?
No, they cannot happen simultaneously because each cell undergo different stage of mitosis.
What did two cells say to each other during mitosis?
Let's split
What happens in each of the three stages that a thunderstorm might have?
During the thrid and final stage of a thunderstorm, all the currents move down. The clouds get smaller as the rain falls from them.(:
What are the three stages of the cell cycle of a eukaryotic cell?
First stage - The cell grows and copies its organelles and chromosomes. During this time, the strands of DNA and proteins are like loosely coiled pieces of thread. After each chromosome is duplicated, the two copies are called chromatids. Chromatids are held together at a region called the centromere. The chromatids each twist and coil and condense into an X shape. After this happens, the cell enters the second stage of the cell cycle. Second Stage - The chromatids separate. The complicated process of chromosone is separation is mitosis. Mitosis ensures that each new cell receives a copy of each chromosomes. Mitosis can be divided into four phases. Third Stage - The cell divides and produces two cells that are identical to the original cell. Cell division will be discussed after mitosis has been described.
Each phase of mitosis?
The four stages of Mitosis is: Prophase: the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes. Metaphase:the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle fibers Anaphase:The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle fiber. Telophase: The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.
What happens to the nucleosomes during mitosis?
During mitosis, the fibers of each individual chromosome are drawn together forming the tightly packed nucleosomes. The tight packing of nucleosomes may help separate chromosomes during mitosis.
What happens during prophase you that does not happen during mitosis?
Prophase is one of the stages in the process of mitosis, the stages of mistosis are : 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase. So metaphase, anaphase, and telophase are what happends in mitosis and does not happen in prophase. And what happens in prophase that does not in mitosis is that the sister chromatids that were formed during interphase have shortened and thickened and are now visible with a light microscope.
Are the stages of mitosis occurs simultaneously on a meristem?
No, they cannot happen simultaneously because each cell undergo different stage of mitosis.
What happens to homologous chromosomes during prophase 1 of meiosis which does not occur during prophase of mitosis?
In mitosis each daughter cell ends up with the same number of chromosomes as the mother cell.
What happens to chromosomes in each mitosis?
I belive that they split apart!
Does mitosis ensure that each new eukaryote cell receives a copy of each chromosome?
Yes, it does! This occurs during G2 phase of Mitosis.
What happens during each each of the two stages of photosynthesis?
These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.
What happens during the four phases of mitosis?
Fist thing that happens is Interphase. This is what a cell spends most of its life in, but it is not part of Mitosis, it is before. Interphase is the duplicating of the cell's chromosomes( which hold the DNA). Next is Mitosis. I remember the four stages of Mitosis by PMAT. First stage of mitosis is Prophase, this is when the membrane surrounding the chromosomes is dissolved. Second stage is Metaphase, the chromosomes line up in the middle in pairs. Third stage is Anaphase, the chromosome pairs separate and go to opposite sides of the cell. Last stage of Mitosis is Telephase, the cell starts to split in half taking one of each chromosome. After Mitosis is Cytokinesis, this is when the membrane forms around the the chromosomes and the 1 parent cell is now 2 daughter cells.
Describe the salient features of each mitotic stage?
Mitosis consists of four main stages: Prophase Metaphase Anaphase Telephase
What did two cells say to each other during mitosis?
Let's split
What happens in telophase II?
Sister Chromatids separate from each other just like mitosis .
What happens during each of the two stages of photosynthesis?
These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.
