Answers
Answer:
Explanation: The various stages of mitosis are:
1. Prophase
The process of mitosis is initiated at this stage wherein coiling and thickening of the chromosomes occurs
Shrinking and hence the disappearance of the nucleolus and nuclear membrane takes place
The stage reaches its final state when a cluster of fibers organizes to form the spindle fibers
2. Metaphase
Chromosomes turn thick in this phase. The two chromatids from each of the chromosomes appear distinct
Each of the chromosomes is fastened to the spindle fibers located on its controller
Chromosomes align at the centreline of the cell
3. Anaphase
Each of the chromatid pair detaches from the centromere and approaches the other end of the cell through the spindle fiber
At this stage, compressing of the cell membrane at the center takes place
4. Telophase
Chromatids have reached the other end of the cell
The disappearance of the spindles
Chromatin fibers are formed as a result of the uncoiling of daughter chromosomes
The appearance of two daughter nuclei at the opposing ends due to the reformation of the nucleolus and nuclear membrane
At this phase, splitting of the cell or cytokinesis may also occur
