Answer:
Interphase: The first phase in mitosis can be split up into G (growth) and S (synthesis) phases. In the first G phase, the cell increases in size. DNA is synthesized here (to synthesize is to produce a substance by a chemical reaction). Once this happens, the cell undergoes the G2 phase where there is more cell growth and proteins are produced.
Prophase.
1) Preprophase:
In plant cells only, the cell remains where it is and the nucleus moves around the cell before the start of mitosis through the formation of a phragmosome. In this formation, pre-prophase is the formation of microtubules ring and pre-prophase band under the plasma membrane.
2) Prophase:
A lot of things happen here. The DNA, RNA and proteins combined together - chromatin - merge into chromosomes which are held together by a centromere. Spindle fibers as well as microtubles are then formed in the cytoplasm and the cells organelles eventually migrate to opposite sides of the cell. As prophase continues, the cell nucleus membrane breaks up and the chromosomes move towards the center of the cell.
3. Prometaphase:
This is the end of prophase and an early stage of metaphase. The nuclear membrane breaks up. In addition, the microtubules occupy the nuclear space. Each chromosome forms two kinetochores.
Metaphase
During metaphase the chromosomes line up at the center of the cell along a metaphase plate, exactly in the middle of the cell where it is equidistant from each spindle pole. The chromosomes line up at the metaphase plate randomly until they eventually attach to each other.
Anaphase
The attached chromosomes break apart and move to the opposite ends of the cell. Once there, the “daughter” chromosomes split apart forming single chromatids again.
Telophase
In telophase, the chromosomes then become sectioned off into new nuclei and daughter cells. These nuclei develop nuclear envelopes and mitosis is basically complete with two new daughter cells. The daughter cells are formed with genetic information passed on from the parent cell.
Cytokinesis
The final step, cytokinesis actually takes place near the end of telophase where the two daughter cells now formed split apart into individual cells.
This is a separate process from telophase that begins at the same time as the telophase.
Hope this makes sense. Feel free to ask further for any info.
